Ultimate Showdown: Logitech G Pro X Superlight 2 vs Razer Viper V4 Pro vs Finalmouse Ultralight X – Which Gaming Mouse Reigns Supreme in 2025?

In the world of competitive gaming, milliseconds and milligrams can make the difference between victory and defeat. In 2025, three ultra-light wireless mice stand at the pinnacle of esports-grade peripherals: Logitech’s G Pro X Superlight 2, Razer’s Viper V4 Pro, and Finalmouse’s Ultralight X. Each of these flagship mice pushes the boundaries in weight reduction, sensor technology, and click latency. All are designed to satisfy professional FPS players and discerning enthusiasts alike. But which one truly reigns supreme in 2025? In this comprehensive comparison, we’ll delve into build quality, weight and ergonomics, sensor and switch performance, wireless technology, latency, battery life, software, and more. We’ll also highlight the latest updates (including new firmware and product releases as of August 2025), summarize expert and pro player opinions, and outline the pros and cons of each model. By the end, you’ll have a clear picture of which mouse is the best fit for your playstyle and needs.

Design & Build Quality

Logitech G Pro X Superlight 2: Logitech’s Superlight 2 sticks to a proven formula. It uses a solid high-quality plastic chassis with no exterior honeycomb cut-outs, giving it a clean look and sturdy feel. At first glance, it’s almost indistinguishable from its predecessor – the shape and dimensions are identical, and even the word “Superlight” remains on the side rather than a “2” prosettings.net prosettings.net. The difference is under the hood: Logitech made subtle tweaks like adding a USB-C charging port (finally replacing the old Micro-USB) and slightly altering the PTFE foot design on the base prosettings.net prosettings.net. The build quality is excellent – the shell has minimal flex or creaking, reflecting Logitech’s reputation for durable construction. The Superlight 2’s coating is lightly textured for grip and resists fingerprints well prosettings.net prosettings.net, ensuring it stays comfortable through long, sweaty practice sessions. Overall, it’s a no-frills design focused on reliability and comfort, which contributes to why so many pro players have stuck with the Superlight shape over the years prosettings.net prosettings.net.

Razer Viper V4 Pro: Razer’s Viper line is known for sleek, low-profile designs, and the upcoming Viper V4 Pro continues that trend. It retains an ambidextrous-friendly form factor with a symmetric shape (side buttons only on the left for right-handed use) and a lightweight yet robust plastic shell. The Viper V3 Pro (its direct predecessor launched in 2024) introduced a major shape overhaul – moving away from the original Viper’s long, flat design to a “boxier and more compact” shape that’s notably similar to Logitech’s Superlight series prosettings.net. This safer, slightly higher-hump shape was a gamble that “paid off dividends” as it resulted in far greater adoption by pro gamers than the older Viper versions prosettings.net. The V4 Pro is expected to keep this successful shape with perhaps minor refinements (some community rumors hoped for a slightly narrower back end for even easier handling reddit.com, but Razer likely won’t stray far from what the V3 Pro perfected). In terms of build, Razer uses a matte textured plastic that many find pleasantly grippy without needing add-on grips prosettings.net. The Viper V3 Pro’s build quality was praised for being solid despite the weight reduction, and we anticipate the V4 Pro to maintain that high standard. One point of feedback on the Viper V3 was that its side buttons could feel a bit mushy prosettings.net; it’s possible Razer will tighten that up in the V4 Pro. The V4 will almost certainly feature USB-C charging (the V3 Pro did), and Razer’s attention to detail (like larger PTFE feet on the V3 for smoother glide razer.com razer.com) should carry forward. Overall, expect the Viper V4 Pro to exude a premium, performance-focused build, balancing lightness and rigidity.

Finalmouse Ultralight X: Finalmouse takes a radically different approach to design. The Ultralight X (often abbreviated ULX) is all about pushing the limits of lightweight construction. It features a distinctive carbon fiber composite chassis with a honeycomb shell pattern, shaving every gram possible finalmouse.com finalmouse.com. In fact, Finalmouse advertises the ULX’s carbon fiber composite has a strength-to-weight ratio three times better than typical ABS plastic and even superior to magnesium alloy finalmouse.com. This material and open honeycomb cut-outs allow the Ultralight X to hit unheard-of weight figures – as low as 31 grams in the smallest model finalmouse.com finalmouse.com! (More on weight in the next section.) Visually, the ULX carries Finalmouse’s signature aesthetic: a minimalist shell (no RGB or extra frills) available in various limited-edition colorways and designs through sporadic drops. Build quality is a bit of a mixed bag, however. On one hand, the materials are high-tech and the mouse feels almost impossibly light and agile. On the other hand, the extreme weight reduction comes with some compromises in rigidity. Testers have noted that the carbon fiber shell can be noticeably flexible under pressure, and if you squeeze or press hard on certain areas (like the underside), you can even separate the shell pieces slightly rtings.com rtings.com. Additionally, the button implementation isn’t as crisp as the competition – both the main clicks and side buttons on the ULX have been described as having a slightly mushy feel rtings.com rtings.com. The scroll wheel also drew criticism for feeling somewhat cheap and not very grippy, with an odd quirk that pressing it from the side can inadvertently trigger a middle-click rtings.com. These build quirks don’t generally affect in-game performance (the mouse still tracks and clicks extremely well, as we’ll discuss), but they do impact the overall feel and perceived quality. It’s clear Finalmouse prioritized absolute weight savings and cutting-edge internals over a luxurious in-hand feel. For enthusiasts, the trade-off is often worth it; however, those used to the sturdy, closed shells of Logitech and Razer might find the ULX’s construction a bit too spartan. One advantage of Finalmouse’s design is that the Ultralight X comes in three sizes – Small (codenamed “Cheetah”), Medium (“Lion”), and Large (“Tiger”) – so you can choose a build that fits your hand size perfectly finalmouse.com. All three sizes share the same overall design and materials, just scaled up or down.

Summary: In terms of build quality, Logitech and Razer deliver tried-and-true sturdiness with refined matte plastic shells, while Finalmouse uses exotic materials to break weight records at the cost of some structural flex and polish. The Superlight 2’s “if it ain’t broke, don’t fix it” approach results in a mouse that feels familiar, durable, and tournament-ready prosettings.net prosettings.net. Razer’s Viper V4 Pro, building on the V3 Pro, should offer a high-quality finish and pro-grade durability in a very light frame, though we’ll watch to see if Razer addresses the minor button feedback issues noted in the previous gen prosettings.net. Finalmouse’s Ultralight X is a marvel of engineering – astonishing to hold, but with some rough edges (literally and figuratively) in build execution rtings.com. Now, let’s examine how these design philosophies translate into weight, shape, and ergonomics.

Weight and Ergonomics

One of the first specs competitive gamers look at is weight. A lighter mouse is easier to flick and track with minimal inertia, which is why all three of these mice are exceptionally lightweight. However, they’re not all the same, and shape/ergonomics play a huge role in how that weight translates to in-hand feel.

• Logitech G Pro X Superlight 2: Weighing in at around 60 grams (officially ~60g +/-) logitechg.com logitechg.com, the Superlight 2 lives up to its name. It’s about 3 grams lighter than the original Superlight and achieves this without resorting to any shell cut-outs – an impressive feat by Logitech’s engineering. The shape is the exact same widely-loved design as the previous model prosettings.net. This means an ambidextrous (symmetrical) shape with a medium size and very “safe” curves. The hump is gently centered and not too pronounced; the sides are subtly concave for grip but have no aggressive grooves; and there’s a slight flare toward the back to cradle your palm prosettings.net prosettings.net. This classic shape has been described as a “one size fits all” or even “potato-shaped” design by the community, meaning it doesn’t force a specific grip style prosettings.net. Most people – palm, claw, or fingertip grippers – can pick up a Superlight and quickly feel at home prosettings.net prosettings.net. It measures roughly 125 mm in length, 63 mm in width, and 40 mm in height (similar to the original GPX) and is thus squarely a medium-sized mouse. For small-handed fingertip grippers it might still be a tad large, but for the vast majority of gamers, the Superlight 2’s ergonomics are almost universally comfortable prosettings.net. This safe shape, combined with the 60g weight and Logitech’s excellent weight distribution (no weird balancing issues), makes the Superlight 2 extremely easy to maneuver for flick shots while still offering enough palm support for stability. It’s no wonder one reviewer noted “I can always pick up a G Pro Superlight and play with it without any issues whatsoever… once I pick it up I feel right at home” prosettings.net.
• Razer Viper V4 Pro: The Viper V4 Pro’s weight hasn’t been officially announced at the time of writing, but based on Razer’s trajectory it will likely be in the same ballpark or slightly lighter than the Viper V3 Pro’s 54 grams prosettings.net. That would make it one of the lightest full-size wireless mice on the market, only slightly heavier than Finalmouse’s ultra-featherweight. The Viper V3 Pro’s shape – which the V4 will inherit with possible minor tweaks – is ambidextrous and medium-large in size. However, unlike the Superlight’s symmetrical hump, the Viper V3/4 shape is optimized for right-handed use in practice (the side buttons are on the left only) and geared especially toward claw and fingertip grip players. Razer describes the V3 Pro shape as a “right-handed symmetrical shape” best for claw/fingertip razer.com, since it has a slightly higher hump towards the back than the original Viper and a more compact length. In fact, the V3 Pro got shorter and taller than the older Viper V2 Pro – this makes it fill the hand a bit more and support the palm for claw grip, whereas the older Viper was longer/flatter which some found too “floaty” for their grip prosettings.net. The new shape is considered much “safer” and less polarizing prosettings.net; many compare it to the GPX’s shape, though the Viper V3 has a slightly wider back end and a subtly different curvature that some users either love or find just okay. If you have medium to large hands and use claw or fingertip grip, the Viper V3 Pro (and thus V4 Pro) is likely a great fit. Palm grip is still possible if your hands are medium-sized, but pure palm grippers with larger hands might prefer a bigger mouse like Razer’s DeathAdder series. Overall, at ~54g and with an esports-refined shape, the Viper V4 Pro promises phenomenal handling. Dozens of pros switched to the Viper V3 Pro immediately after launch because of how stable yet agile it feels – one of the “best debuts we’ve ever seen” for a mouse, according to ProSettings.net prosettings.net prosettings.net. Expect the V4 Pro to continue that trend, giving players a confidence-inspiring balance of speed and control.
• Finalmouse Ultralight X: Here’s where things get extreme. The Ultralight X’s defining trait is its ridiculously low weight. Finalmouse offers three sizes, each with its own weight: 31 g (Small), ~35 g (Medium), and ~37 g (Large) – with a small variance of a couple grams per unit rtings.com rtings.com. These weights are measured without the PTFE feet attached, but even with feet the medium we tested was only ~38 g in total rtings.com rtings.com. For context, that’s nearly half the weight of the Superlight 2. Holding the Ultralight X truly feels like holding nothing at all – Finalmouse even quips it weighs less than a few packets of sugar or less than a single strawberry finalmouse.com. In-game, the ULX glides with virtually zero effort, which can potentially improve reaction time for rapid flick shots or quick lateral hand movements. Of course, weight isn’t everything – the shape has to be comfortable to control that weight. The Ultralight X’s shape is derived from Finalmouse’s earlier designs (like the Starlight-12 and Air58), which in turn took inspiration from classic esports mice (it’s somewhat reminiscent of the Zowie FK series or early Finalmouse Ultralight Pro shape). It’s a symmetrical shape with a low profile. The hump is quite low and centered, and the sides are gently curved – overall it’s a very flat mouse with no aggressive ergonomic flares. This makes it ideal for fingertip grip or a relaxed claw grip. Palm gripping a mouse this small and light is less common, especially in the smaller variants. Finalmouse themselves note the ULX shape “is best suited for claw and fingertip grip types” due to the low hump and slim, medium-length body rtings.com. The medium (Lion) ULX has dimensions roughly similar to a Zowie FK2 or Finalmouse Starlight Medium – a comfortable medium size that suits many hands (Finalmouse mentions it’s the same dimensions as the Starlight-12 Medium edition) rtings.com. The Small (Cheetah) ULX is truly tiny – great for pure fingertip or very small hands – and the Large (Tiger) ULX gives a bit more length and height for those who found previous Finalmouse offerings too small finalmouse.com. No matter the size, all ULX models share that weightless feeling and extremely nimble handling. However, because of the low-profile design and ultra-light mass, the ULX can initially feel a bit “floaty” or hard to control for some users coming from heavier mice. It has almost no inherent momentum, which is a double-edged sword: it’s effortless to fling around, but if you’re used to a mouse with more heft, you might overshoot your flicks until you adjust. Many aim enthusiasts swear that once you adapt, a sub-40g mouse lets you push your aim potential even further. The availability of three sizes also means you can optimize ergonomics – Finalmouse basically says “no matter your grip style or hand size, there will be an Ultralight X optimized for you” finalmouse.com. That’s a compelling proposition for those very particular about fit. Just keep in mind that the ULX does have those honeycomb holes (some users don’t like the feel of holes against their fingers or worry about dust ingress, though it hasn’t proven a major issue in practice). In summary, the Ultralight X offers an unparalleled weight advantage and a good, albeit fairly conventional, ambidextrous shape to make the most of it. It favors claw/fingertip grips and skilled hands that can leverage its hyper-responsiveness. If you value lighter-than-air swipes and don’t mind a somewhat lower profile shape, the ULX will feel like a revolution in ergonomics.

Ergonomic Considerations: All three mice forego dedicated right-handed ergonomic shapes (like pronounced thumb grooves or pinky rests) in favor of ambidextrous-friendly designs that maximize fast, even handling. The Logitech and Razer have solid shells which some users find more comfortable (no hole pattern texture) and arguably a more planted feel due to being slightly heavier. The Finalmouse, on the other hand, prioritizes reducing inertia at the potential cost of a bit of comfort and stability. This means the “best” ergonomics ultimately depend on your preferences and grip. If you want a safe shape that almost anyone can use comfortably, the Superlight 2 is the champion prosettings.net prosettings.net. If you want a shape slightly more tuned for claw grips and aggressive maneuvers, the Viper V4 Pro’s shape (as proven by the V3 Pro’s popularity) is fantastic – many pros now consider it the new gold standard for FPS mice prosettings.net prosettings.net. And if you’re willing to adapt to an ultra-light, low-profile design to potentially gain an aiming edge, the Ultralight X will reward you with unmatched agility.

Sensor Performance

When it comes to raw sensor specs and performance, these mice are at the very cutting edge. All three are equipped with flagship-grade optical sensors that can track at absurd DPI levels and speeds far beyond what any human could realistically use. More importantly, they all offer flawless tracking – no prediction, no acceleration, and minimal lift-off distance – suitable for the highest level of competitive play. Let’s break down each:

• Logitech Superlight 2 – HERO 2 Sensor: Logitech introduced a new HERO 2 sensor in the Pro X Superlight 2. While the previous Superlight’s HERO sensor was already top-tier (up to 25,600 DPI), the HERO 2 pushes the envelope even further. Logitech advertises it at up to 25K+ DPI, with the capability of reaching a staggering 40,000+ DPI after a firmware update (they cite “44K DPI” maximum) logitechg.com logitechg.com. Of course, nobody is playing at such DPIs – the point is that the sensor has enormous overhead for precision. More relevant is the tracking speed and accuracy: the HERO 2 can handle speeds over 500 inches per second and up to 40–88 G acceleration without losing tracking logitechg.com logitechg.com. In real terms, it’s essentially impossible to make this sensor malfunction with normal play – you can swipe as fast as you physically can and it will keep up. Logitech’s HERO series sensors are also famed for their power efficiency (a big reason for the mouse’s long battery life, as we’ll see later). In testing, the Superlight 2’s wireless sensor performance is rock solid – as expected from Logitech, there’s no jitter or filtering beyond a minimal smoothing at extremely high DPI. The HERO 2 is not a mere DPI bump; Logitech improved things like motion consistency and added a unique “sensor calibration” feature via G HUB. This allows users to essentially measure and sync their true sensitivity by moving the Superlight 2 alongside another mouse to calculate the real DPI difference, and also independently adjust X/Y axis sensitivity and lift-off distance logitechg.com prosettings.net. It’s a handy tool for perfectionists wanting precise tuning. Bottom line: the Superlight 2’s sensor is overkill in the best way. While some rivals might tout higher polling or DPI, in actual tracking fidelity the HERO 2 is a known quantity – extremely stable and flawless prosettings.net prosettings.net. As one reviewer put it, this sensor brings Logitech mice “to 2023 and beyond,” delivering the reliable tracking and wireless freedom that pros demand prosettings.net prosettings.net.
• Razer Viper V4 Pro – Focus Pro Next-Gen Sensor: Razer has been at the forefront of sensor tech, often collaborating with PixArt to create custom sensors. The Viper V3 Pro uses the Focus Pro 30K/35K Optical Sensor (Gen-2), capable of 30,000+ DPI and known for its 99.8% resolution accuracy razer.com razer.com. In fact, the V3 Pro’s sensor supports features like smart tracking, asymmetric cut-off (custom LOD), and Motion Sync – all aimed at maximizing consistency and precision razer.com razer.com. For the V4 Pro, rumors and leaks indicate Razer will debut an even more advanced sensor. One insider note suggests a new PixArt sensor with double or triple the processing speed and 50% more stable wireless detection, which Razer will have first access to in 2025 reddit.com. This likely implies improved data throughput (to facilitate higher polling rates and more responsive motion synchronization) and even more robust wireless signal handling. Some speculate this could be a “Focus Pro 39K” or similar, but Razer hasn’t confirmed the exact specs yet. Regardless, we can expect the V4 Pro to match or exceed the V3’s specs: at least ~35,000 DPI max, tracking speeds of 750+ IPS, and impeccable accuracy. The Viper V3 Pro’s sensor already delivered “outstanding all-around sensor performance” rtings.com, and was arguably the most advanced on the market in 2024 prosettings.net prosettings.net. The V4’s sensor will continue that legacy. One key feature Razer emphasizes is Motion Sync (synchronizing the mouse’s signal updates with the PC’s polling intervals for more consistent movement processing) razer.com. The new sensor is rumored to have on-sensor Motion Sync – meaning the synchronization is handled on-chip rather than via software, potentially reducing latency further finalmouse.com. This aligns with PixArt’s latest tech and should make the tracking even smoother. In short, the Razer V4 Pro will have an elite sensor, perfectly suited for pro play. Any one of these mice can be said to have “flawless” tracking, but Razer’s might take the crown for fastest processing and richest feature set. If you need things like ultra-fine DPI adjustments (Razer allows single DPI steps and even has a sensitivity clutch or stages programmable) razer.com razer.com, or if you want to fine-tune lift-off distance per surface (the asymmetric cut-off has 26 levels) razer.com, Razer’s software and sensor combo gives you that granularity. Ultimately, though, at default settings and standard DPI, you’d be hard-pressed to tell a difference in raw accuracy between the Focus Pro and HERO 2 – both are beyond reproach.
• Finalmouse Ultralight X – PixArt PAW3395 Sensor: The Ultralight X might surprise some with its sensor choice: it uses PixArt’s flagship PAW3395 (the same top-tier sensor found in many high-end mice from brands like Razer’s competitors and Logitech’s third-party competition). Finalmouse doesn’t brand it fancy, but they did leverage it to its fullest. The PAW3395 is rated for 26,000 DPI, over 650 IPS, and 50G+ acceleration, plus it supports Motion Sync and other modern features on silicon. Finalmouse advertises it as the “latest generation PixArt sensor with on-chip motion sync” finalmouse.com – highlighting that the sensor itself handles synchronization tasks for reduced latency. In testing, the ULX’s sensor performance is, as RTINGS puts it, “outstanding all-around … more than suitable for gaming at any competitive level.” rtings.com rtings.com Tracking is flawless and feels just as good as Logitech’s or Razer’s implementations in real play. The DPI range of the ULX covers all common low/high sens needs (400 to 26,000 DPI adjustable, likely through the XPanel app). Finalmouse likely chose the 3395 to also achieve their 8000 Hz polling target (since this sensor has a faster internal SPI reporting capability compared to older sensors). There’s no customizable surface calibration or LOD tweaking tool publicly known for the ULX, but the default LOD is low (as preferred by FPS gamers) and, thanks to the on-chip calibration, remains consistent on various pads finalmouse.com. One area the ULX truly excels is click latency – which, while not solely sensor-dependent, reflects the total performance package. In 8000Hz mode, RTINGS measured the ULX’s click latency at ~1.2 milliseconds, which is incredibly low for a wireless mouse rtings.com rtings.com. This suggests Finalmouse optimized the firmware and sensor interplay for speed (we’ll discuss wireless latency more soon). In summary, the Ultralight X’s sensor might not have a fancy marketing name, but it’s absolutely a top-tier performer. It “unlocks new possibilities for your aim” as Finalmouse boldly claims finalmouse.com, in the sense that there is zero fallback – any miss is on you, not the mouse’s tracking. One could argue the ULX is actually pushing the sensor hardest by pairing it with 8 kHz polling (something Logitech’s HERO 2 also now does, and Razer’s will). All things equal, the differences among these sensors are extremely minor. As one reviewer noted about the HERO 2 vs. competitors: “technically isn’t the fastest or most cutting edge sensor on the market (since wireless mice beyond 2000Hz exist), but in reality we’re talking extremely thin margins here” prosettings.net. The same holds between all three – their sensors are all effectively perfect in game, with differences measured mostly by advanced labs or only felt on the most high-end systems. The ULX does have one disadvantage: Finalmouse’s software doesn’t currently allow button remapping, but regarding sensor settings it provides the essentials (DPI, polling, etc.), which the PixArt sensor handles expertly.

Overall sensor verdict: You simply can’t go wrong with tracking on any of these mice. All three will deliver pixel-precise aim with no spin-outs or skips, even under the fastest flicks a pro player could throw at them. The Logitech HERO 2 emphasizes efficiency and consistency prosettings.net logitechg.com, Razer’s Focus series emphasizes ultimate speed and configurability (especially with features like Smart Tracking and asymmetric cut-off for lift-off tuning) razer.com razer.com, and Finalmouse leverages PixArt’s best to complement their ultra-light design rtings.com finalmouse.com. It’s a testament to how far gaming mice have come that sensor fidelity is no longer the differentiator – it’s the combination of sensor with weight, shape, switches, and wireless tech that really sets these apart.

Switches & Buttons

The feel and reliability of the clicks are another crucial factor for competitive mice. Misclicks or double-click issues can be fatal in competition, and the responsiveness of the buttons can subtly affect reaction times. Here’s how each mouse approaches it:

• Logitech – Lightforce Hybrid Optical-Mechanical Switches: One of the headline upgrades in the G Pro X Superlight 2 was the move to Logitech’s new Lightforce switches for the main left/right buttons logitechg.com logitechg.com. These are a hybrid design that uses optical actuation for speed and durability, combined with a mechanical spring tension to mimic the crisp feel of traditional mechanical switches. The idea is to get the best of both worlds – optical means no debounce delay and no degradation into double-clicks (optical switches don’t develop the “double click” issue that mechanical metal contacts do, because there are no contacts that wear out) prosettings.net. Meanwhile, the mechanical element preserves that snappy, tactile feedback that pro players are used to, instead of the sometimes hollow or overly soft feel that early optical switches had. In practice, the Lightforce switches on the Superlight 2 feel excellent – very similar to the crisp clicks of the original GPX (which used Omron 20M mechanicals) but with a slightly sharper rebound and zero wobble. Logitech claims these opticals are “satisfying mechanical feel” with the speed and reliability of optical logitechg.com logitechg.com. Indeed, during use we found no difference in click latency between the Superlight 2 and other top-tier mice – it’s instantaneous and rated for long life. No more worrying about your mouse developing a double-click after a year of heavy use. The side buttons on the Superlight 2 remain mechanical (likely high-quality switches similar to before) and are well-placed and tactile. Logitech’s side buttons have always been decent – not too soft, not too hard. There’s minimal post-travel and a satisfying click on the Superlight 2’s side buttons, making them reliable for quick utility actions (like pulling out abilities or switching weapons). The scroll wheel on the Superlight 2 is a standard notched wheel (no infinite scroll or tilt-click here – pure FPS focus). It’s rubberized and quiet, with defined steps that are neither too stiff nor too loose. All in all, Logitech’s button implementation is rock-solid. The main clicks in particular stand out for giving the Superlight 2 the confidence pros need without impact to battery life (as Logitech puts it) logitechg.com. Note: One of the original GPW/Superlight’s only downsides was occasional double-click issues due to mechanical Omron wear; the Superlight 2’s Lightforce switches definitively solve that prosettings.net. So reliability is a huge pro here.
• Razer – Optical Mouse Switches (Gen-3 and beyond): Razer was actually first to widely adopt optical switches in gaming mice (starting with the Viper Ultimate’s Gen-1 in 2019). By the Viper V3 Pro, they were up to Gen-3 Optical Mouse Switches, which are fantastic. These switches have a 90 million click lifespan and actuate in just 0.2 ms with no debounce delay razer.com razer.com. They are true opticals (no mechanical components causing debounce), so like Logitech’s Lightforce, they eliminate double-click concerns and are extremely fast. Many users love Razer’s optical switch feel – it’s crisp and rigid, with a clean break and very low pre-travel. If anything, the Gen-3 opticals in the Viper V3 Pro were even tighter than Logitech’s hybrid; some might describe them as a tad less “springy” and more “fast and hard” in click sensation. We expect the Viper V4 Pro will use an improved Gen-4 Optical Switch, possibly with an even higher durability rating (Razer’s DeathAdder V4 Pro just launched with Gen-3, so V4 might introduce Gen-4 later, but Razer could surprise us). In any case, the main clicks on the Viper series are renowned. For example, one pro reviewer stated the clicks “feel great” prosettings.net and of course have zero chance of double-clicking in the middle of a tournament prosettings.net prosettings.net. The side buttons on the Viper V3 Pro had a bit of a mushy reputation prosettings.net. They weren’t awful, but compared to the super crisp main clicks, the side buttons had more travel and a softer response. Razer might address this in the V4 Pro (perhaps new switch or thicker pad under them). Still, they are well positioned (slightly elevated and towards the middle of the left side) and large enough to hit easily. The scroll wheel on the Viper V series is rubberized and has distinct steps – on the V3 Pro, it had a nice tactile bump for each notch which is good for weapon swapping consistency. Razer doesn’t do tilt scroll in the Viper (to save weight), and that’s fine for FPS. One more thing: the Viper V3/V4 has a small button on the bottom of the mouse. By default, this bottom button toggles power/DPI (press and release for DPI cycle, press and hold for power) razer.com. It’s also reprogrammable if you want to set it as a different function (though bottom placement means it’s not for in-game use). Logitech, by contrast, has no DPI button at all on the Superlight (you must use software or attach the included DPI puck). Finalmouse similarly doesn’t provide a DPI cycle button on top. So Razer giving a DPI/power button – albeit on the underside – is a small convenience for on-the-fly sensitivity swaps if you memorize the sequence. In terms of overall feel: if you like snappy, fast clicks, Razer’s implementation is top-notch. The optical Gen-3/Gen-4 switches make spam-clicking feel instantaneous and reliable. And like Logitech, Razer’s optical switches ensure you “never have to deal with any accidental double clicks” cropping up prosettings.net. The only critique is those side buttons, but even if they remain a touch squishy, they function perfectly well – and in heat of gameplay that’s a minor note.
• Finalmouse – Custom Mechanical Switches (Omron 20M): Interestingly, Finalmouse took a more old-school route for the Ultralight X’s mains: they use mechanical switches – specifically Omron D2FC-F-7N 20M-rated switches for the main clicks rtings.com. These are the classic switches used in many gaming mice a few years ago. Why would Finalmouse stick to mechanicals when opticals are all the rage? Possibly to save weight or due to simplicity – an optical switch mechanism might add a bit more weight or require more power. It could also be that Finalmouse prioritized a certain click feel or had supply considerations. In any case, the main clicks on the ULX have a very light actuation force. Finalmouse engineered a new “Ultralight Click Tensioning” system that significantly reduces the spring force required to click finalmouse.com finalmouse.com. Their philosophy is that ultra-lightweight clicks complement an ultra-lightweight mouse, reducing any barrier between your input and the resulting action. Indeed, the clicks on the ULX are extremely low-resistance – you can register clicks with very little pressure. Some hardcore aim trainers love this, as it potentially increases click speed and reduces finger fatigue. However, the implementation has drawn some community critique: those light clicks, combined with the somewhat mushy feeling noted earlier, mean the ULX’s click feel isn’t as crisp or snappy as the Logitech or Razer. RTINGS commented the buttons feel “slightly mushy” rtings.com, which could be due to the combination of the switch and tensioning design. They are certainly not firm or tactile in the way opticals are. It’s a very soft click – some might describe it as “damped.” On the upside, these Omrons give a familiar feel and are time-tested. On the downside, mechanical switches can eventually develop double-click issues as they wear (Omron 20Ms are rated 20 million clicks, less than the lifespan of the others). Heavy users might find after a year or more that double-clicks could emerge – it’s not guaranteed, but it’s a possibility that simply doesn’t exist on the optical-switch competitors. For a $200 mouse built for ultimate performance, some find this choice puzzling. Finalmouse presumably decided the trade-off was worth it for weight or feel reasons. The side buttons on the Ultralight X are also mechanical and are fairly standard in size/placement (two on the left side). They feel okay – not particularly remarkable. The reduced overall build rigidity means there’s a hint of flex when pressing side buttons hard, but during normal use it’s fine. Scroll Wheel: The ULX’s scroll has been a point of complaint: it’s reportedly a bit loose-feeling and the scrolling steps are not very well-defined. The wheel’s plastic/rubber coating is also noted as not very grippy rtings.com. A peculiar flaw: you can accidentally click the middle button by pushing the wheel sideways (the wheel can wobble and actuate the switch) rtings.com. This suggests a less refined scroll mechanism. In FPS games, the scroll wheel is mostly for weapon swaps or bunny hopping (in games like CS), so a slightly flimsy wheel isn’t a deal-breaker, but it does underscore that Finalmouse’s engineering priorities lay elsewhere (weight, polling).

In summary, each mouse has a different philosophy for clicks. Razer and Logitech have converged on optical solutions to ensure speed and longevity – with Razer’s feeling sharp and fast, and Logitech’s hybrid aiming to feel as close to traditional as possible while still reaping optical benefits logitechg.com prosettings.net. Finalmouse, conversely, sticks with traditional mechanical switches but tweaked to be extremely light to press finalmouse.com. If you’re sensitive to click feel: the Superlight 2 and Viper V4 Pro will give you more pronounced, crisp feedback, whereas the Ultralight X’s clicks will feel softer and lighter. Reliability-wise, you can trust that a year or two down the road, the Superlight 2 and Viper won’t misfire (no double-click demons) prosettings.net prosettings.net, whereas the Ultralight X might require a switch replacement eventually if used heavily. For many pros, that trade-off in the ULX might be acceptable to get the lightest clicks and weight possible, but it’s something to weigh (no pun intended).

Wireless Technology and Latency

All three mice are wireless and aim to deliver wired-like performance in terms of latency and stability. However, their approaches and capabilities differ, especially when it comes to polling rates and proprietary wireless tech:

• Logitech Lightspeed (2.4 GHz) – Now up to 8000 Hz: Logitech’s Lightspeed wireless has long been regarded as one of the most reliable and tournament-proof wireless technologies. The Superlight 2 uses an updated Lightspeed implementation that, at launch, supported a 1000 Hz polling rate out of the box (just like its predecessor) but was quickly updated via firmware to support 2000 Hz, and eventually even 4000 Hz and 8000 Hz in early 2024 prosettings.net reddit.com. Logitech’s official spec now touts “up to 8 kHz polling” in the Superlight 2 logitechg.com, which is a huge jump. Achieving 8 kHz wirelessly is non-trivial, but Logitech managed it thanks to the HERO 2 sensor’s power efficiency and a new “Lightspeed High-Speed” mode. According to their marketing, it’s designed for tournament-grade reliability even in high interference environments at these speeds logitechg.com. Practically, to use 8000 Hz on the Superlight 2, you just need to update the mouse and receiver firmware via G HUB reddit.com – no special dongle purchase required. Once updated, you can toggle polling rates (125, 500, 1000, 2000, 4000, 8000 Hz) in Logitech G HUB prosettings.net prosettings.net. At 8 kHz, the mouse is sending data every 0.125 milliseconds, which is incredibly fast. Does it improve your gameplay noticeably? On a high refresh monitor, rapid flicks can feel slightly smoother at 4K or 8K Hz polling prosettings.net, but we are indeed talking very thin margins. Logitech themselves played it safe at first with 1000–2000 Hz, probably because beyond that returns diminish and CPU usage increases. Still, having the option means the Superlight 2 is future-proof – as games and systems optimize for higher polling, this mouse is ready. In terms of latency, independent testing has shown the Superlight 2’s wireless latency at 1000 Hz is effectively on par with wired, and at 2000+ Hz it can even slightly surpass older wired mice in click responsiveness. The difference is a few hundred microseconds – nothing a human can reliably detect in blind tests reddit.com. The key point is Logitech’s wireless is trusted by pros – over a quarter of all pro FPS players were using a Superlight at one point prosettings.net prosettings.net, and they wouldn’t if there were any signal hiccups or lag. Lightspeed has proven its mettle on stage. The Superlight 2 continues that legacy, with plenty of bandwidth to spare. It uses a dedicated USB-A dongle (now USB-C via adapter or built-in if you have a newer hub) and can also interface with Logitech’s Powerplay mat (though Powerplay charging mode fixes polling at 1000 Hz to conserve power). The signal stability is excellent – you can be in a LAN event with dozens of wireless mice and interference and still have no issues. Logitech’s firmware and hardware design minimizes any packet loss or smoothing. And with that new dual signal rate, even jitter-sensitive aimers found it exceptionally smooth.
• Razer HyperSpeed + (Wireless) – 4000 Hz and beyond: Razer’s HyperSpeed is their low-latency 2.4 GHz wireless tech, and it has also proven to be top-tier. With the Viper V2 and V3 Pro, Razer introduced an optional HyperPolling Wireless Dongle that allowed those mice to poll at 4000 Hz wirelessly (instead of the standard 1000 Hz). On the Viper V3 Pro, out of the box it’s 1000 Hz, and with the add-on dongle, you can lock it to 4000 Hz razer.com razer.com. The upcoming Viper V4 Pro is expected to push this further. It’s very possible Razer will include 4000 Hz capability natively (without needing a separate dongle) or even go for 8000 Hz wireless if the new sensor and hardware support it. Some leaks suggest the new PixArt sensor and wireless chip could handle 8K, putting it on par with Logitech and Finalmouse’s 8K claims reddit.com finalmouse.com. At the very least, Razer will ensure the V4 Pro isn’t behind Logitech’s offering, so we anticipate either a bundled upgraded dongle or built-in support for higher polling. In any case, Razer’s wireless latency at 1000 Hz is as low as it gets (their mice consistently rank among the lowest click latency). At 4000 Hz with the current HyperPolling dongle, click latency can drop slightly further (~2.0 ms to ~1.5 ms ranges, similar to Logitech’s 2K/4K performance). These differences are microscopic. Razer’s wireless has also been proven in competition; many esports players (especially those sponsored by or partial to Razer) have used Viper Ultimate/V2/V3 Pros in tournaments without issue. The HyperSpeed protocol uses adaptive frequency hopping and other tricks to maintain a stable connection. During our time with Viper mice, we’ve experienced no random disconnections or interference issues – it’s rock solid. The only caveat: the 4000 Hz mode (and presumably any 8000 Hz mode if offered) dramatically increases CPU usage and can lead to diminishing returns if your system or game isn’t prepared. Some users of the 4K dongle noted that not all games handle 4K polling smoothly (some engines may stutter if mouse input rate is unexpectedly high). This is a general issue, not Razer-specific – it applies to Logitech and Finalmouse at 8K too. For optimal use, you need a strong CPU and possibly limit ultra-high polling to games that can benefit and handle it. Otherwise, running at 1000 or 2000 Hz might give a better experience with no “polling hiccups” reddit.com reddit.com. Razer’s advantage is giving that choice and, likely, integrating it more seamlessly in the V4 Pro. Also, note that Razer’s wireless supports one-to-many pairing (the standard 1000 Hz HyperSpeed dongles can connect certain mice to one dongle, though ironically some users wanted a 1k dongle for laptops to pair with a Viper that came with the 4k dongle, which wasn’t allowed reddit.com). It’s a bit complex in Razer’s lineup – but essentially, Razer might include both a high-speed dongle and normal one in the future, or allow flexible pairing. We’ll see.
• Finalmouse Starlight Wireless Tech – Dual MCU at 8000 Hz: Finalmouse had to engineer something special to reach 8000 Hz polling wirelessly on the Ultralight X. They revealed that their dongle uses a dual microcontroller architecture – one dedicated solely to the radio communication, and one to handling the USB interface at high speed finalmouse.com. This effectively turns the wireless link into a high-bandwidth channel that can flood the USB at 8 times the normal full-speed rate. In other words, the ULX’s receiver operates in USB High-Speed mode (which is required for >1000 Hz polling) and splits tasks between two chips to keep latency ultra-low finalmouse.com. The result is that the Ultralight X can indeed sustain up to 8000 Hz polling wirelessly, matching the fastest wired mouse (Razer had an 8000 Hz wired mouse, the Viper 8K, but this is wireless). In testing, it works – though one has to use Finalmouse’s configuration (XPanel) to set the polling rate. The click latency and motion latency are phenomenally low. As mentioned, RTINGS clocked the ULX at around 1.1–1.3 ms input latency at 8kHz rtings.com rtings.com, which is essentially on par with or slightly better than Logitech and Razer’s 1000 Hz results. At 1000 Hz, the latency would be around 2+ ms, so 8k does shave perhaps ~1 ms off – a tiny edge that only really matters in bragging rights or perhaps for the absolute most hardware-sensitive players. In terms of connection stability, Finalmouse’s previous wireless mice (Starlight-12) sometimes had firmware quirks, but the Ultralight X so far has been generally stable. The dual-MCU dongle approach presumably helps maintain a consistent report flow. Finalmouse’s wireless is also 2.4 GHz and should be fine in most environments, though it hasn’t been field-tested as widely as Lightspeed or HyperSpeed in big LAN tournaments. Early community feedback hasn’t highlighted any major connection flaws, so that’s a good sign. It’s also worth noting Finalmouse doesn’t support Bluetooth or multi-device pairing – it’s a pure one dongle, one mouse setup focused on performance (the same is true for Logitech and Razer – these are all tournament mice, so no Bluetooth mode). The ULX’s wireless did have one trade-off: to conserve power at lower polling or idle, Finalmouse likely employs aggressive power saving. There might be a slight wake-up delay if the mouse has been idle (we’re talking fractions of a second). But during active use, no latency spikes were observed. Signal integrity is something Finalmouse specifically bragged about – they claim their innovations ensure “packets are delivered 8 times faster” with no compromises finalmouse.com. Given the complexity, that’s an achievement. Ultimately, Finalmouse’s wireless tech in the ULX is cutting-edge, but one should be mindful that running at 8000 Hz constantly will tax your system. As one Redditor bluntly advised about 8k on these mice: “You don’t need 8000. I recommend that you don’t use it… 2000-4000 Hz is the sweet spot unless you have a monster CPU” reddit.com. This sentiment is echoed by many – higher polling can cause diminishing or even negative returns (like frame drops) if the game doesn’t support it well reddit.com reddit.com. So, while Finalmouse gives you the full 8k blast, you might choose to dial it down for practical gaming sessions. The good news is the ULX performs excellently even at standard 1000 Hz – the ultra-light weight arguably contributes more to the feel than the ultra-high polling in most cases.

Latency overall: At standard settings (1000 Hz), all three mice have a click latency around 2 ms or less, which is effectively instantaneous from a human perspective. With their respective high-polling modes, they can cut that roughly in half (to ~1 ms), but the real-world advantage of that is debatable prosettings.net reddit.com. Still, for bragging rights and future competitive standards, it’s great that none of these mice will be the bottleneck. If a game in 2025+ starts expecting ultra-high input rates, these devices are ready. Also, from a reliability standpoint: Logitech and Razer have long track records of excellent wireless performance under pressure. Finalmouse is newer in the wireless game, but they’ve clearly invested a lot into making sure their implementation stands up – early adopters haven’t reported lag or cut-out issues en masse, which is a relief given how ambitious 8k wireless is.

In sum, the wireless tech in all three mice is state-of-the-art. Logitech’s Lightspeed offers proven stability and now extreme speeds (8k) with a simple firmware update reddit.com logitechg.com. Razer’s HyperSpeed (with HyperPolling) was the pioneer of >1k wireless polling and is likely to match 8k in the V4 Pro, ensuring Razer remains on the forefront. Finalmouse’s ULX shows that even a smaller company can break technical barriers, delivering 8k wireless through clever engineering finalmouse.com finalmouse.com. At the end of the day, any of these mice will give you a wire-free experience with the responsiveness needed for competitive gaming. The days of fearing wireless latency are long gone – as evidenced by how many top professionals now use wireless mice exclusively in tournaments.

Battery Life & Charging

High performance wireless is great, but it’s moot if your mouse dies mid-match. Battery life is a critical practical concern. Lighter mice have smaller batteries, and higher polling can drain those batteries faster. Here’s how our three contenders manage power:

• Logitech Superlight 2: Thanks to the efficiency of the HERO 2 sensor and Logitech’s power optimization, the Superlight 2 boasts up to 95 hours of battery life on a single charge (with constant motion at 1000 Hz polling) amazon.com newegg.com. This is a notable improvement over the original Superlight, which was around 70 hours. Even at the default 1000 Hz, 95 hours is a lot of gaming – that could be 2 weeks or more of typical daily play sessions before needing a recharge. If you increase the polling rate to 2000 Hz or higher, battery life will drop (though Logitech hasn’t published exact figures for those modes). Empirically, running at 2000 Hz might reduce life to around 50-60 hours, and 8000 Hz could bring it down further to perhaps ~25-30 hours or less of constant use. Still, even a couple dozen hours is plenty for a few days of intense gaming, and the majority of users will likely stick to 1000 or 2000 Hz for a balance of battery and performance. The Superlight 2 charges via USB-C – a very welcome upgrade from the micro-USB of its predecessor prosettings.net. It supports play-and-charge, although the cable is a bit stiff for playing (Logitech includes an adapter to use the cable as an extension for the dongle, which is nice). One standout feature is compatibility with Logitech’s Powerplay wireless charging mat (specifically the new Powerplay 2 system) logitechg.com. If you have the Powerplay pad, the mouse can draw power wirelessly while you use it, essentially giving you infinite battery at the cost of being on that specific mousepad. Powerplay does limit the polling to 1000 Hz mode for technical reasons, but for many that’s an acceptable trade if they want zero charging hassle. Without Powerplay, charging the Superlight 2 from empty to full takes a couple of hours. It also has an LED indicator that blinks when battery is low (and the G HUB software can show a precise percentage). Considering its long life, most users will only plug it in once every week or two for a top-up – or just leave it plugged for a short session and it juices up quickly. Logitech’s battery management is intelligent: the mouse can go to a sleep mode when not used for a bit, and it wakes near-instantly when you move it. In practice, it’s hard to actually run this mouse dry unless you forget to charge it for many days.
• Razer Viper V4 Pro: The Viper V3 Pro was rated for up to 90 hours at 1000 Hz prosettings.net, and we expect the V4 Pro to be in the same ballpark, possibly a bit less if it has higher polling active by default. Razer’s focus was also on cutting weight, so they likely used a similarly sized battery as the V3 (which was around 300 mAh). With the HyperPolling dongle at 4000 Hz, battery life of the Viper V3 Pro dropped significantly – users reported somewhere around 24–30 hours of continuous use at 4K Hz, which makes sense given the increased report rate. If the V4 Pro supports 8K Hz, running that constantly might reduce it further (perhaps under 20 hours). However, Razer could mitigate this with better power-saving in the new sensor or by shipping a larger battery if they found a way without adding weight. It’s speculation, but let’s assume roughly: ~80-90h at 1000 Hz, ~20-30h at max polling. Like Logitech, Razer will almost certainly include a smart “low power mode” when idle to conserve juice, and likely an adjustable sleep timer via Synapse. Charging is done through USB-C as well (Razer switched to USB-C on their mice starting with Viper V2 Pro). Razer often includes a nice lightweight Speedflex charging cable that you can plug in to use the mouse in wired mode if needed. There’s also the option to purchase a separate Razer Mouse Dock (if they update it for V4) – currently, Razer sells a dock that works with some models (like Viper Ultimate dock, etc.), but the V3 Pro did not support the old dock because it had no built-in contact points. The V4 Pro might introduce a new optional dock, but nothing confirmed. Regardless, charging via cable is straightforward and fairly quick (a full charge in under 2 hours). Razer also has an LED indicator (usually on the mouse or via the power button LED) to show battery level (green, yellow, red states). One thing to note: Razer’s HyperSpeed allows for using the mouse in wireless mode while charging from the PC, effectively making it wired temporarily (the cable provides power, but data still goes over wireless). Or you can plug the cable into the mouse and use it as a standard wired USB device; either works. In short, the Viper V4 Pro will comfortably last through long practice days on a single charge at standard settings. If you push its polling to the limit, you’ll need to charge more frequently – perhaps every 2-3 days if using 8K (if available) heavily. That’s a compromise early adopters of high polling have accepted for the performance edge.
• Finalmouse Ultralight X: Finalmouse claims an almost unbelievable figure: “with intermittent use gamers can expect to reach an average of two months without needing to charge” finalmouse.com rtings.com. Let’s break that down. “Intermittent use” likely means a few hours a day at a relatively low polling rate (maybe 1000 Hz). If true, two months suggests roughly 60 days maybe ~2-4 hours a day = ~150-200 hours of total use on one charge. That sounds too high for a tiny 37g mouse, and indeed it probably is optimistic. Finalmouse themselves footnote that continuous use will vary with polling rate, and that their 2-month figure assumes low daily usage and likely 1000Hz rtings.com. RTINGS suspects this is an optimistic scenario and notes that at higher polling or longer play sessions, you might be charging every few days rtings.com rtings.com. The ULX’s battery size isn’t specified, but given the weight, it must be quite small (maybe on the order of 250 mAh or less). However, Finalmouse’s firmware might heavily modulate power usage. For example, at 1000Hz the mouse might be very efficient, and only when you toggle to 8000Hz does it draw significantly more power. It’s conceivable that at 1000Hz, if you only play 1 hour a day, it could last many weeks. But real-world reports indicate that intensive use, especially at high polling, drains it much faster. If you’re using 8000Hz polling in long sessions, you might need to charge the ULX after ~10-20 hours of active use. One clue: Some competitive players who got the ULX reported needing to charge roughly weekly with moderate use, which aligns more with ~30-40 hours of usage between charges (likely at high polling settings). The ULX does have a battery level indicator (it will warn you in the XPanel or via an LED when low) rtings.com. Charging is via USB-C as well (Finalmouse finally moved from their old Micro USB on the Starlights to USB-C on the ULX). It includes a USB-C cable, though RTINGS criticized it for being a bit stiff and “cheaper feeling” than previous Finalmouse cables rtings.com rtings.com. You can absolutely play while charging, but since the ULX is so light, playing wired even with a flexible cable might tug a bit – luckily it charges pretty quickly due to the small battery. Considering use cases: if you’re not a pro grinding 8 hours a day, the ULX can probably last at least a week or two per charge on moderate settings. If you are grinding or keep it at 8k 24/7, just get in the habit of charging it each night or every other night to be safe. The “two months” claim is likely marketing for casual usage scenarios. In a tournament situation, you’d fully charge beforehand and be fine for the day. One thing Finalmouse lacks is any ecosystem like a charging dock or wireless pad – you’ll need to plug it in. Given how small and light it is, some users actually remove the skates and use the included grip tape to open the mouse and manually check the battery (not recommended unless you know what you’re doing). But generally the software indicator is sufficient.

Charging Tech and Extras: None of these mice support Qi wireless charging (aside from Logitech’s proprietary Powerplay as mentioned). All rely on wired charging. The good news is all three use USB-C, so you can use the same cable for any of them and not worry about older connectors. They also all support fast data rates over their cables if used in wired mode (though most will stick wireless).

To sum up battery: Logitech leads in rated longevity (95h at 1kHz) newegg.com and has the unique benefit of Powerplay continuous charging for those who invest in it. Razer offers around 80-90h at 1kHz prosettings.net which is plenty, and even at 4kHz you get through a full day or two of play. Finalmouse touts extremely long standby life, but real continuous gaming at high settings will eat through its tiny battery faster – still, it should cover a solid gaming session or three before needing juice rtings.com. All things considered, none of these mice are prone to dying quickly under normal competitive use if kept at default polling. They’ve struck a fine balance between weight and battery capacity. Just remember to top them up occasionally – or in Logitech’s case, slap it on a Powerplay mat and basically never think about charging at all.

Software & Customization

The software ecosystem (or lack thereof) for each mouse can affect your experience in terms of customization, macros, and updates. Here’s what to expect:

• Logitech G HUB (Superlight 2): Logitech’s G HUB software is the central hub for configuring the Superlight 2. With G HUB, you can customize DPI levels (in increments of 50 DPI, or even 1 DPI steps via config files), set up profiles with different sensitivity or button mappings, program the lone extra button (the Superlight has 5 buttons: L/R, scroll click, and two side buttons – plus technically a DPI switch on the underside if you use the included puck; that puck can be replaced with a PTFE insert) prosettings.net prosettings.net. G HUB also allows you to adjust the Lift-Off Distance (LOD) by using the calibration tool: essentially, you can set how low the mouse can be lifted before the sensor stops tracking, which is crucial for FPS players who do a lot of repositioning. Additionally, the sensor calibration tool mentioned earlier lets you match sensitivity between mice or verify true DPI logitechg.com prosettings.net. The Superlight 2 also supports on-board memory – once you set up a profile in G HUB (DPI, polling, etc.), you can save it to the mouse so it will remember settings even on PCs without G HUB. This is important for tournament use where installing software might not be allowed. Logitech’s software is generally stable and has a clean interface, though some find it a bit heavy for just mouse configuration. The good thing is you don’t need G HUB running in the background all the time; once your settings are applied, the mouse can operate without it. However, G HUB does handle firmware updates, like the crucial one that unlocked 8k polling, so it’s worth keeping it installed for that purpose reddit.com reddit.com. Logitech also provides integration with other Logitech gear through G HUB (if you have Logitech keyboards, etc., you can manage all in one place). One minor note: the Superlight 2 has no RGB lighting at all (which most competitive players prefer – nothing to distract or drain battery), so there are no lighting controls needed in software aside from a single indicator LED.
• Razer Synapse (Viper V4 Pro): Razer’s Synapse 3 software will be used to configure the Viper V4 Pro. Synapse allows a deep level of customization: from DPI stages (the V3 Pro allows 5 stages, and you can set them in 1 DPI increments which is as granular as it gets) razer.com razer.com, to polling rate, to programming all buttons (Razer’s mice often have a Hypershift function too, which lets you assign a secondary function layer if you hold a modifier). The Viper V4 Pro, like the V3, likely has on-board memory for at least one profile (the V3 Pro can store 1 profile with custom DPI, button binds, etc. on the mouse) razer.com razer.com. That’s great for tournament use – you can set it up beforehand and not rely on Synapse on the competition PC. Synapse also provides features like Macro recording (handy if you use the mouse for other genres or productivity – though in pure competitive FPS, macros are rarely used) and inter-device communication (for instance, you could synchronize a Razer keyboard’s profile shift with your mouse, etc.). Unique to Razer’s sensor features, Synapse lets you toggle things like Motion Sync (though Razer typically keeps it on by default and doesn’t allow disabling it anymore), Surface Calibration/Smart Tracking (which auto-calibrates LOD for whatever surface, often no user action needed, but advanced users can fine-tune), and Asymmetric Cut-off which is setting separate lift-off and landing distances razer.com. For example, you could have the sensor stop tracking at 1mm lift but not resume until it’s 2mm close to the surface to avoid accidental movements on touchdown – a niche tweak for very precise preference. Synapse is known to be somewhat heavy (it’s a running joke that Synapse uses a decent chunk of RAM and occasionally needs internet connectivity for full functionality). However, Razer has improved it over the years and for the Viper V3 Pro they ensured that once a profile is stored on-board, you don’t need Synapse running to have your settings. Some in the community prefer to uninstall Synapse after configuring, to reduce background processes – that’s feasible, but you might reinstall it when firmware updates or new settings are needed. As of 2025, Synapse is Windows-only (no Mac version for these latest devices), whereas Logitech G HUB has both Windows and macOS versions. That’s something to consider if you plan to use the mouse on a Mac for non-gaming – you won’t be able to run Synapse on macOS to configure it (though the mouse will still function as basic HID and you’ll have whatever settings you last applied in Windows).
• Finalmouse XPanel (Ultralight X): Finalmouse took a novel approach by creating XPanel, a driverless web-based configurator finalmouse.com finalmouse.com. This means you don’t install a traditional program; instead, you go to a special webpage (xpanel.finalmouse.com) with the mouse connected, and it allows you to adjust settings. The advantage is that it’s lightweight and platform-independent (as long as you have a modern web browser, presumably it works on Windows and potentially Mac via the web – though I believe it might require the Finalmouse dongle to be connected for the page to interface). The XPanel lets you change DPI, polling rate, and see certain telemetry about the mouse (like battery level). It’s aimed at enthusiasts who don’t want bloated software. However, XPanel has limitations: notably, as RTINGS highlighted, it does not allow button remapping rtings.com rtings.com. So the five buttons on the ULX are fixed to their default functions (left click, right click, middle click, side button 1, side button 2) with no easy way to change them (you could use third-party programs like reWASD or X-Mouse Button Control if you desperately wanted a side button to be a different key, but it’s not built-in). This is a downside in terms of flexibility. There’s also no way to do macros or custom profile switching on the fly – Finalmouse keeps it minimal. On the flip side, many competitive players don’t need fancy mappings or macros; they just set their DPI and go. Finalmouse likely figured their audience would not miss the extra software fluff. The ULX also doesn’t have RGB, so no lighting controls necessary. One cool thing: XPanel being driverless means once you configure settings, the mouse retains them and you don’t need to run anything in the background. Finalmouse can also deploy firmware updates through XPanel if needed (for example, to fix bugs or improve performance). Historically, Finalmouse has been slow with software updates, but the ULX is a more mature product, so we’ll see. The community often points out that Finalmouse tends to rely less on software and more on out-of-box tuning – which means fewer things to adjust, but also fewer things that can go wrong in software.

Compatibility: All three mice primarily target Windows PC use. They will work on Mac or consoles in basic modes (since they are standard USB HID devices), but without the respective software, you can’t change settings on those platforms. Logitech’s Superlight 2 will default to whatever DPI/profile is on-board if used on Mac/console, and you can’t run G HUB on console at all (on Mac you can run G HUB to configure since Logitech supports macOS officially for their gaming mice). Razer doesn’t support consoles or Mac with Synapse, but again, you can use the on-board profile on those systems. Finalmouse’s XPanel might be accessible on Mac via browser (if their web utility supports Safari or Chrome on Mac, which likely it does). So if you needed to tweak the ULX on Mac, it might be possible through the web app – an interesting advantage of that approach.

Another aspect of software is community profiles or integrations. Logitech and Razer sometimes allow profile auto-switching when launching games (but since these mice have few buttons, that’s not a big deal for FPS). Neither Logitech nor Razer likely have game-specific configs by default for these, aside from what users set. Finalmouse obviously is too niche for that.

One more note: Firmware updates. Logitech delivered a key firmware update enabling 8kHz – showing they support the device post-launch reddit.com reddit.com. Razer might do similar if, for instance, they launch V4 at 4kHz and later unlock 8kHz if hardware allows. Finalmouse could update for bug fixes. It’s important to have the means to update firmware: G HUB and Synapse make it easy, XPanel presumably also handles it (Finalmouse did release firmware for Starlights via a separate app, but hopefully XPanel streamlines that).

Macro/advanced usage: If you use your gaming mouse for other tasks, know that Logitech G HUB can do things like assign complex macros or keystrokes to buttons (though with only two side buttons, there’s limited real estate). Razer Synapse can as well, including things like launching programs or using their Hypershift for a second layer. Finalmouse intentionally avoids macros – they cater to pure aim performance with no extras.

In summary, Logitech’s software is robust and generally user-friendly, focusing on core settings and a few unique tools (sensor calibration) logitechg.com. Razer’s software is extremely feature-rich (some might say overly so), allowing for in-depth performance tweaks and customization if you need them razer.com razer.com. Finalmouse’s approach is minimalistic – set your essentials and forget it rtings.com rtings.com. Depending on what kind of user you are, you might prefer one over the others. If you love tinkering and macro’ing, Razer gives the most options. If you want to avoid bloat entirely, Finalmouse is refreshing in its simplicity. And if you want something in between, Logitech offers plenty of customization without being too heavy-handed, plus the comfort of a very stable software experience.

Price & Availability

Finally, let’s talk about the more pragmatic side: how easy (or hard) it is to get each of these mice and what it’ll cost you.

• Logitech G Pro X Superlight 2: Logitech launched the Superlight 2 in late 2023 with an MSRP of around $159.99 USD. This price is a premium, but it’s in line with what high-end wireless mice have been running (the original Superlight was $149). Given its popularity and Logitech’s distribution, the Superlight 2 is widely available at major retailers, online stores, and often even at a slight discount during sales. You can find it in multiple colors – typically Black, White, and Pink, which Logitech released at launch logitechg.com. Sometimes Logitech does special editions or team collaborations; for example, the original had limited edition colors, and it wouldn’t be surprising if the Superlight 2 gets a special skin or two down the line. Logitech provides a 2-year warranty logitechg.com, and their customer support is generally well-regarded if you run into issues. All in all, buying a Superlight 2 is straightforward: it’s in stock at Amazon, Best Buy, etc., and you know exactly what you’ll pay. Logitech’s scale means the price is stable (and might even drop a bit over time). If $160 is steep, you might find it for ~$140 on sale occasionally. But remember, you’re getting top-notch tech and reliability for that price.
• Razer Viper V4 Pro: At the time of writing (August 2025), the Viper V4 Pro is either just launching or about to launch. We can infer its price based on Razer’s trend: The Viper V3 Pro launched at $149.99, the DeathAdder V4 Pro launched at $149. So the Viper V4 Pro will likely be around $150 USD as well. If Razer includes the 4000Hz/8000Hz capable dongle in the box this time, the price might be slightly higher (maybe $159 to account for that accessory). But Razer might also sell two versions (one with a HyperPolling dongle bundle, one without). Either way, expect ~$150-160. Razer products are also widely available through big retailers and their own Razer Store. They usually come in at least Black and sometimes White versions at launch. Razer also did special editions of the Viper V3 Pro (like a Faker Edition in collaboration with League of Legends pro, and a Sentinels Edition for a Valorant team) razer.com razer.com. Those had unique colors but same hardware, often at a slight markup. We might see similar collaborations for V4 Pro if it gains popularity (imagine a team-branded V4 Pro, etc.). Razer offers a 2-year warranty typically on mice and has decent support, though experiences vary. Since the V4 Pro is new, availability might be a bit constrained in the first weeks, but given Razer’s size, it should be broadly in stock. It’s not a limited item – you won’t have to fight to get one beyond maybe a short initial demand rush. Price-wise, Razer often holds MSRP for a while on new releases, but you might see minor sales ($10-20 off) during holidays a year later. Being an investment in a flagship, most serious users budget for that full price.
• Finalmouse Ultralight X: Here’s where things diverge. Finalmouse doesn’t follow the traditional retail model. The Ultralight X was sold via Finalmouse’s website in timed drops, and it came in different editions (like the initial “Competition” series in a carbon fiber raw finish, and later the “Prophecy” series with colors). The base price was around $189 – $200 USD for the mouse, depending on edition. Finalmouse also often charges for shipping, and any import taxes if you’re international. The big kicker is availability: Finalmouse mice are produced in limited batches and sell out almost instantly when the drop happens. For instance, when the Ultralight X first went on sale, it reportedly sold out in minutes (if not seconds) with thousands of units gone. If you didn’t snag one, the only way was to buy from resellers or scalpers on eBay, who sometimes list them at inflated prices. Historically, some Finalmouse releases doubled or tripled in price on the secondary market (e.g., the Starlight-12 had crazy resale at launch). However, the community notes that the resell hype has calmed down somewhat recently – ULX resells might be only slightly above retail now, as supply has increased and hype normalized reddit.com reddit.com. Still, it’s not as simple as clicking “add to cart” any day you want. You have to either catch a drop (Finalmouse usually announces on social media and you have to be ready at the exact time) or pay a premium later. Some people also suspect Finalmouse deliberately does short supply to drum up hype (one Reddit user colorfully said “Finalmouse is a trash company ran by clowns…never will give a single dollar to them” out of frustration reddit.com). That’s an extreme view, but it underscores the sentiment: buying a Finalmouse can be an event in itself. Limited editions: Finalmouse also tends to theme their mice – the ULX had a “Competition” edition (with no holes on sides for structural reasons, slightly heavier around 38g, and costing even more). Then the “Prophecy” edition came with desert-themed colors for the ULX (the drop referenced in a Reddit thread) reddit.com reddit.com. Those are cosmetic variants but same hardware. Price might vary, but expect around $200. Warranty from Finalmouse is typically 1 year, and their customer support has a mixed reputation. Some users have had trouble getting timely responses on issues. And unlike a local store purchase, returns or exchanges can be complicated and at Finalmouse’s discretion (their refund policy is pretty strict unless item is defective) reddit.com reddit.com. So essentially, with Finalmouse you pay top dollar for bleeding-edge tech and minimal weight, but also endure a less convenient buying process and potentially less support. On the flip side, there’s a sort of exclusivity or cool factor – you know you have a mouse that not everyone can easily get, and that can feel special. Finalmouse also engages in heavy influencer marketing (partnering with big streamers or pros like TenZ, whose signature mouse sold out fast). This can drive demand beyond supply.

From a pure value perspective: The Logitech and Razer, while expensive, come from big brands that offer easy warranty, broad availability, and often you get extras in the box (Logitech gives grip tape and an extra PTFE puck; Razer sometimes includes grip tape, a 4k dongle in bundles, etc. – V3 Pro included grip tape and a spare set of feet). Finalmouse gives you basically the mouse, dongle, cable, and that’s it (they did include some grips and maybe extra skates in the competition edition box, but support items were minimal). If something goes wrong out of warranty, with Logitech/Razer you might still find parts or DIY fix guides easily (and you probably paid less to begin with). With Finalmouse, if, say, a switch breaks after 1.5 years, you’re largely on your own (or have to source parts and be willing to mod it).

So, the cost of entry for the Ultralight X is higher and the cost of ownership could be higher as well. Yet, for those who absolutely crave that performance and have the budget, it’s often worth it. A telling quote from a discussion: “They just make everything limited edition. It sells out in 30 seconds then scalpers post them for 3x the price and hype nerds buy them up.” reddit.com This slightly tongue-in-cheek remark highlights that Finalmouse is in a category of its own – almost like a collectors’ item that also happens to be a gaming tool. Not everyone will want to jump through those hoops for a mouse, and that’s okay – Logitech and Razer provide readily attainable alternatives.

Verdict on pricing: If you want the easiest, most reliable purchase – Logitech’s Superlight 2 is the way to go (and its price, while high, often reflects in resale value too – it holds value decently and you know lots of users out there if you ever needed community help or spare parts). If you want top tech without the hassle – Razer’s V4 Pro gives you essentially everything Finalmouse offers in performance (minus a few grams of weight difference) at a similar price but without scarcity. If you want the absolute lightest and are willing to pay a premium (both in cash and effort) – Finalmouse ULX is your pick, just be ready to move fast on drops or pay above MSRP secondhand.

Now, with all aspects covered, let’s distill the main advantages and disadvantages of each mouse, and then wrap up with which might be “supreme” for different types of gamers.

Pros and Cons for Each Model

Logitech G Pro X Superlight 2 – Pros & Cons

Pros:

• Extremely Comfortable & Universal Shape: Safe, medium-sized ambidextrous design that suits almost all grip styles and hand sizes without issue prosettings.net prosettings.net. It’s a shape that “fits most hands and grips” and has essentially become the industry standard for a reason prosettings.net prosettings.net.
• Solid Build Quality: Sturdy unibody shell with no holes, excellent coating grip, and durable construction that can withstand heavy use. Despite being only ~60g, it doesn’t feel flimsy at all.
• Lightning-Fast & Reliable Wireless: Logitech’s Lightspeed wireless is proven in competition – virtually zero latency or dropouts. Now with up to 8000 Hz polling capability, it’s as cutting-edge as any wireless on the market logitechg.com. Even at standard settings, the connection is flawless and responsive prosettings.net prosettings.net.
• Long Battery Life: Up to ~95 hours on 1ms polling newegg.com, meaning you can game for days or weeks between charges. Efficient HERO 2 sensor and power management give it one of the best battery performances in its class.
• Next-Gen Sensor Performance: The HERO 2 sensor is exceptionally accurate and consistent (up to 25K+ DPI). Tracking is “flawless” with no smoothing, and Logitech’s added features like on-board DPI calibration and independent X/Y sensitivity tuning are great for enthusiasts logitechg.com. No issues with spin-outs or LOD – it’s rock solid.
• Optical-Mechanical Hybrid Switches: The Lightforce main clicks are crisp and fast, with optical reliability (no double-click ever) but a satisfying mechanical feel logitechg.com logitechg.com. This addresses one of the only weaknesses of the original (mechanical switch wear) and gives confidence in every click.
• Strong Software & Customization: G HUB is feature-rich but straightforward. You can fine-tune everything (DPI, polling, LOD, button binds, macros) and then store your settings on the mouse memory. The sensor calibration tool is a unique bonus for perfectionists prosettings.net. And if you don’t want to run the software, you don’t have to – the mouse will remember your last config.
• Ecosystem & Extras: Comes with grip tape and an extra PTFE foot cover in the box. Compatible with Logitech’s Powerplay wireless charging system for infinite battery during use logitechg.com. Also available in multiple colors to match your setup.
• Wide Availability & Support: Easy to purchase from many retailers, with a 2-year warranty and Logitech’s reliable customer support network. No drama or uncertainty in getting or replacing one. Plus, a huge community of users (guides, spare parts, etc. are easy to find).

Cons:

• High Price Tag: It’s on the expensive side for a gaming mouse (around $150-$160 MSRP) prosettings.net. You’re paying a premium for the Logitech brand and tech – there are cheaper mice that also have good specs (though arguably none with all the Superlight’s strengths combined).
• Conservative Evolution: Some critics felt the Superlight 2 didn’t innovate dramatically over the original prosettings.net. It’s largely the same shape and only slightly lighter, so if you expected a radical redesign or a weight drop into the 50g range, that didn’t happen. It’s more “evolutionary, not revolutionary” in upgrades like sensor and USB-C, which, while useful, aren’t flashy logitechg.com.
• One Size/Shape Only: Unlike Finalmouse which offers multiple sizes, Logitech bets on a one-size-fits-all. If you have extremely large hands or very specific ergonomic shape preferences, the GPX2 might feel too generic. It doesn’t cater to those who want a pronounced ergonomic shape or a smaller mini version (though its safe shape is a plus for most, it’s a con if you’re in the minority who don’t love it).
• No On-Board DPI Button: There’s no quick DPI toggle on top. The only way to change DPI on the fly is to flip the mouse and use the underside button or have preset profiles in G HUB (or use the optional puck with button). This is a minor gripe since many FPS players stick to one DPI, but it’s worth noting if you switch DPI for tasks.
• Minimal Aesthetics & Features: The Superlight 2 is laser-focused on performance. That means no RGB lighting, no Bluetooth mode, no extra buttons (no sniper button or DPI clutch, etc.). While none of those are needed for competitive play (and many would consider them positives to leave out), a casual user looking for a multi-genre mouse might find it too spartan. Basically, it’s built to excel in FPS, not to wow with bells and whistles.
• Stock Feet Just OK: The PTFE feet on the GPX2 are decent but not the fastest or smoothest out there (Logitech went for a mid-range glide to please most users) prosettings.net. Enthusiasts might end up swapping to aftermarket skates for a glide of their preference, and note that the foot design changed slightly so old Superlight feet aren’t compatible prosettings.net. A small annoyance if you had a stash of skates.
• Debatable 8k Usefulness: While it can do 8000Hz polling, running that mode could stress systems and isn’t broadly supported in games yet reddit.com reddit.com. So one could argue it’s an overkill feature. Also, initial firmware didn’t have it – it required an update reddit.com – but at least that’s been addressed now. If you don’t update, you’re capped at 1000/2000 Hz, but most users will update via G HUB anyway.

Razer Viper V4 Pro – Pros & Cons

Pros:

• Elite Performance Hardware: With a rumored next-gen Focus Pro sensor and native high polling wireless, the V4 Pro is poised to deliver “pretty much the best specs you can get right now.” prosettings.net Expect true 1:1 tracking, 99.8% resolution accuracy, and flawless performance even at absurd speeds razer.com razer.com. Plus, out-of-the-box 8000Hz wireless polling (or at least 4000Hz) means it’s ready for the most demanding aim enthusiasts prosettings.net.
• Improved Safe Shape: The Viper V3/V4 shape is a big success – more accommodating and hand-filling than earlier Vipers, making it a “lot safer” and more universally liked prosettings.net prosettings.net. It still caters to claw/fingertip players especially, providing great stability and control for rapid flicks. Many pros who found the old Viper too flat now love the V3 Pro’s comfort. In other words, you get an ergonomic boost without sacrificing the low-profile agility.
• Feathery 54g Weight (Approx): Razer managed ~54g on the V3 Pro without resorting to holes, and the V4 Pro should be similar or even lighter prosettings.net. This means excellent maneuverability and reduced fatigue, yet with a solid shell (no flex issues). It’s the lightest major-brand mouse of its class, only bested by Finalmouse.
• Optical Switches (No Double-Clicks): Razer’s Gen-3 Optical switches have a fantastic reputation for reliability and speed. They actuate in 0.2ms and won’t develop double-click problems razer.com razer.com. They also feel very satisfying – crisp and tactile. You can spam-click or tap-fire with confidence that every shot registers with minimal delay. Essentially zero debounce means you’re limited only by your finger speed.
• Grippy Coating & Quality Feet: The Viper V3 Pro’s coating was praised for being “smooth, yet easy to grip.” razer.com It doesn’t get slippery with sweat. Also, Razer uses high quality pure PTFE feet – large ones on the Viper that glide very smoothly (and they often include a spare set). Combined with the low weight, the mouse moves effortlessly.
• Strong Battery (for its Weight): ~80-90 hours at 1000Hz is great endurance given the lightweight design prosettings.net. Even using it wirelessly with high polling, it will last through long practice days – and a quick charge brings it back thanks to USB-C. It also can charge to a usable level pretty fast (a few minutes of charge gives hours of play).
• Comprehensive Customization: Razer’s Synapse software, while hefty, offers a ton of tuning: per-game profiles, macro recording, detailed sensor adjustments (you can even calibrate the exact tracking distance cut-off if you want) razer.com. You can remap any button, including assigning secondary functions via HyperShift. DPI can be set in single increments if you’re that granular razer.com. Basically, no other software gives as much control. And you can save one profile on-board to use the mouse sans software at tournaments razer.com.
• On-mouse DPI & Power Button: Unlike Logitech (which lacks a quick DPI toggle on top), the Viper has a multifunction button on the underside. By default a quick press swaps DPI (with preset stages like 400/800/1600/etc.) and a long press turns the mouse on/off razer.com. While not as convenient as a top button, it’s still easier than needing software if you occasionally switch sensitivities (some players might go to a low DPI for photo editing then back to high for gaming, etc.). Also, being able to power off the mouse without software is handy for travel or ensuring it won’t wake in your bag.
• Pro Player Validation: The Viper V3 Pro had one of the best receptions among pros – over 400 pros were using it by mid-2025, which is a huge endorsement prosettings.net prosettings.net. It’s now arguably “the new benchmark for gaming mice,” as one expert reviewer stated prosettings.net. The V4 Pro will build on that momentum. Top Valorant and CS players (like Zekken, who even tested a prototype V4 Pro in matches prosettings.net) are already on board. So you know it’s a mouse trusted at the highest level of competition.
• Availability in Special Editions: Razer often does cool collabs (e.g., Team or player-branded editions) razer.com. These can be pros if you like cosmetic variety. Even if you just get the standard, you might have color options (Black and White are typical, maybe others later). And if you’re a fan of, say, T1 or Sentinels, a branded version can be a fun collector’s item with the same performance.

Cons:

• Premium Price: Priced around $150 (and possibly a bit more if a HyperPolling dongle is included), it’s a serious investment. It’s on par with Logitech’s pricing, meaning you’re paying a lot for marginal gains. Some might find better value in slightly older models (like the Viper V3 Pro might drop in price) that offer 90% of the performance.
• Side Buttons Could Be Better: A known weak point on the Viper V3 (and likely V4 if unchanged) is that the side buttons aren’t as crisp as on some competitors prosettings.net. They have a bit of post-travel and a softer click. While they work fine for things like map pings or melee attacks, the feel is a touch mushy, which is a small letdown in an otherwise flagship device.
• Synapse Dependency (for advanced tweaks): To unlock all features (like 8kHz polling settings, custom cut-off, etc.), you need Razer Synapse on Windows. Synapse has a reputation for being resource-heavy and occasionally buggy. If you dislike running manufacturer software, you might be annoyed. The mouse does have on-board memory for one profile, but initial setup still needs Synapse. On a locked-down system (like a work PC or tournament PC without Synapse), you’re limited to what you set beforehand.
• No Bluetooth / Limited to 2.4GHz: Like the others, it’s purely a performance mouse. No Bluetooth mode for casual use or multiple device connectivity (not really a con for its intended use, but just to mention). If you wanted one mouse to also quickly connect to a laptop via BT for non-gaming, this isn’t it.
• Battery Life Dips at High Polling: As mentioned, running at 4000 Hz cuts battery life significantly (to maybe ~24h of constant use), and if 8000 Hz is enabled, it could be even shorter. This means if you choose to play at the absolute max settings, you’ll be charging very frequently (possibly daily after long scrims). It’s a trade-off: performance vs endurance. At least it charges fast via USB-C, but it’s not a “set and forget” if you’re pushing the tech.
• One Size Fits Most: The Viper’s shape, while improved, still might not please everyone. It’s slightly wider and taller than the Superlight, which some small-handed users might find a tad bulky for pure fingertip grip. Conversely, it’s not as large as an ergonomic mouse – very large hands might still find it a bit small. There’s no “Viper Mini Pro” at the moment (though rumor mills say Razer might do a smaller version in the future). So, if you have very unique hand size requirements, the V4 Pro might not cater specifically to you.
• No Wall Charger or Fancy Dock Included: Minor nitpick – at $150, it’s all about the mouse. Razer doesn’t include a USB wall adapter or a charging dock in the box. If you want a charging dock, that might be a separate purchase if Razer releases one compatible. Not a big con, but considering some lower-priced wireless mice include docks, it’s worth noting.
• Potential Overkill & CPU Load: Running at 8000Hz (if supported) is extreme and many games don’t benefit or even handle it properly reddit.com reddit.com. If you enable it, you might encounter issues like lower FPS or inconsistent game performance unless your PC is very high-end and the game is optimized for it. Essentially, one con of the V4 Pro’s maximum capabilities is that you might dial them down in practice to avoid unintended consequences. So you might pay for features you can’t fully utilize yet.

Finalmouse Ultralight X – Pros & Cons

Pros:

• Unprecedented Lightweight Design: At 31–37 grams across its size range, the Ultralight X is by far the lightest wireless gaming mouse available finalmouse.com rtings.com. This featherweight build enables incredibly fast flicks and effortless long swipes, potentially improving aim for those who can harness it. It literally “breaks every benchmark” for weight, making other mice feel heavy by comparison finalmouse.com. If you value a superlight mouse, the ULX stands alone.
• Three Size Options: Unlike one-size-fits-all competitors, Finalmouse offers Small, Medium, and Large variants (Cheetah, Lion, Tiger) finalmouse.com. This means you can choose a mouse that truly fits your hand – a big advantage for those who have smaller or larger than average hands or very specific grip preferences. Each size is optimized for performance, so you don’t sacrifice much by going up or down in size beyond slight weight differences rtings.com. This level of choice is rare in the high-end mouse market.
• High-Tech Materials (Carbon Fiber Composite): The ULX’s chassis uses a custom carbon fiber composite that boasts a strength-to-weight ratio better than plastic or even magnesium finalmouse.com. This allows it to be ultralight yet reasonably strong. It’s a showcase of engineering innovation, and many find the textured carbon fiber feel to be unique and premium in its own way. There’s also an option (Competition edition) with solid sides (no holes) for those who prefer that aesthetic/feel, still at a very low weight.
• Unrivaled Wireless Polling (8000 Hz): The Ultralight X can reach 8000 Hz polling wirelessly, which is cutting-edge finalmouse.com. Finalmouse’s dual-microcontroller wireless system ensures ultra-low latency and fast packet delivery, making it arguably the most advanced wireless tech in a gaming mouse currently finalmouse.com. At 8kHz, it delivered <1.3ms click latency in tests rtings.com, basically setting a new standard. If you’re an input latency fanatic, this mouse gives you bragging rights as having the fastest setup (as long as your PC can keep up).
• Outstanding Click Latency & Consistency: Even aside from polling, the ULX’s clicks are extremely low latency. The internal processing is optimized for every microsecond finalmouse.com finalmouse.com. Combined with the light actuation force of the tensioned Omron switches, it feels very responsive – there’s “nearly no resistance” to your click inputs finalmouse.com. This can make rapid fire and quick-tap actions feel almost instantaneous.
• Superb Sensor Performance: Using PixArt’s flagship PAW3395 with Finalmouse’s custom tuning, the ULX offers “outstanding all-around sensor performance” suitable for the highest competitive level rtings.com rtings.com. Tracking is flawless, with no jitter or spin-out issues. The inclusion of on-sensor Motion Sync ensures consistent tracking without software tricks finalmouse.com. In essence, you get perfect tracking plus the latest latency improvements – the best of both worlds.
• Aim-Focused Design Philosophy: Everything about the Ultralight X is geared toward aim performance. There’s no extra buttons, no RGB, no gimmicks – just shape, weight, sensor, and switches honed for FPS. Many top aimers appreciate this purity. It’s a tool built with one purpose: to maximize your aim potential. Features like the Ultralight Click Tensioning and the high polling are all in service of that goal finalmouse.com. If you’re an aim training enthusiast or someone who chases ever better Kovaaks scores, the ULX gives you an edge (or at least, removes any hint of hardware limitation).
• Decent Battery Life at Moderate Settings: While 8kHz will drain it faster, if you run the ULX at 1000Hz (which is still fine for most matches), the battery life can last quite long – Finalmouse claims up to weeks of use on a charge with intermittent play rtings.com. Users have reported that at sensible polling and daily usage, it does last multiple days to a week or more, meaning you don’t have to charge it every single night. Its idle power draw is very low, so it conserves battery when not in active use.
• Collector’s Item Appeal: Finalmouse has a certain prestige and hype in the gaming community. Owning one can feel special because of the limited releases and the brand’s almost cult following. The ULX, especially limited colorways like the “Prophecy” editions with unique designs, has aesthetic appeal as well as performance. If you care about style in addition to function, Finalmouse often delivers unique looks. Even the unpainted carbon fiber “Raw” finish has a high-tech allure to it.
• No Bloat Software: The XPanel web configurator is minimal and driverless finalmouse.com. It doesn’t install anything on your PC or hog resources in the background. You just set your DPI/polling and go. Many people find this refreshing compared to big suites like Synapse or G HUB. Less software running means potentially less can go wrong mid-game.

Cons:

• Extremely High Cost & Limited Availability: With an MSRP around $189 and often only obtainable via limited drops, the Ultralight X is both very expensive and very hard to get reddit.com reddit.com. It’s not sold in regular stores, and you may need to wait for a restock or pay scalpers. This makes it impractical for many – not everyone can or wants to drop $200+ on a mouse or deal with split-second drop purchases. In short, it’s an exclusive item, and that exclusivity is a double-edged sword for consumers.
• Durability Concerns (Flex & Mushy Feel): The aggressive weight reduction comes at a cost to sturdiness. The carbon fiber composite shell, while strong for its weight, is noticeably flexible in places rtings.com rtings.com. Squeezing the sides or bottom can produce flex or creaking, which undermines the sense of quality. Additionally, the main clicks, due to the very light tension, feel slightly mushy rather than crisp rtings.com. Some users may perceive this as a downgrade in tactile feel compared to firmer switches. The scroll wheel also feels cheap and can wobble enough to misfire clicks rtings.com. These issues combined make the ULX feel less solid than its competitors – you’re trading some build integrity for weight. In worst cases, pressing hard on the mouse can actually separate shell segments momentarily rtings.com. So if you have a heavy grip or tend to clamp the mouse, that’s a concern.
• Mechanical Switch Longevity: Finalmouse used Omron 20M mechanical switches for the mains rtings.com, which, while tried-and-true, are known to potentially develop double-click issues over time as the contacts wear. This is exactly the problem Logitech and Razer moved away from by going optical. So the ULX might be susceptible to double-clicks down the line with extensive use. Given the mouse’s cost and limited support, having to self-repair or replace switches in a year or two would be frustrating (and could void warranty).
• Sparse Features (No Buttons or Macros): The ULX has no side on-board memory for multiple profiles (it just retains last used settings) and no software-level customization beyond DPI/polling rtings.com. You cannot rebind buttons or set macros through XPanel – it doesn’t support it rtings.com rtings.com. If you use side buttons for anything fancy (e.g., push-to-talk, macros in other games, etc.), you’ll need third-party tools. The mouse essentially assumes you only care about pure aiming and nothing else. This lack of flexibility can be a con if you ever want to use the mouse outside of its FPS comfort zone.
• Short Warranty & Support Challenges: Finalmouse typically offers a 1-year limited warranty and has a smaller support infrastructure. Many users have reported slow or unhelpful customer service from the company. If something goes wrong (like a faulty unit or a part breaking), getting a replacement might be slower or more uncertain than with Logitech/Razer. Since availability is limited, you can’t just walk into a store for an exchange. For a ~$200 device, that’s a concern – the after-sales support doesn’t match the premium price.
• Frequent Charging at Max Performance: While battery life is good at 1000Hz, if you actually use the ULX at 8000Hz regularly, expect to charge it much more often (possibly every couple of days of heavy play) rtings.com. Also, the included charging cable was noted to be stiffer and of lower quality than competitors rtings.com rtings.com, which makes playing while charging a bit more cumbersome. It’s a minor inconvenience, but at this price, one would hope for a nicer cable.
• Potential Overkill & System Stress: Running 8000Hz wireless demands a lot from your PC. As mentioned earlier, not all games or systems handle it gracefully – some may experience frame drops or unstable performance with 8k input reddit.com reddit.com. So you might dial it down to 4k or 2k in practice, which begs the question: do you really gain much over say a 4000Hz Razer in real gameplay? For most, the answer is likely no – the differences are extremely subtle. You may find yourself moderating the ULX’s capabilities to balance your overall system performance. So the big headline feature might not translate to a big advantage in reality, at least not yet.
• Community Criticisms: There’s a portion of the enthusiast community that’s skeptical of Finalmouse’s hype and marketing. Complaints include them “overpromising… lying about the weight, awful drops, [and] stupidly high price tag” reddit.com. While the product is genuinely innovative, these criticisms highlight that Finalmouse’s reputation isn’t spotless. So depending on who you ask, using a Finalmouse might invite some teasing about falling for hype. That’s not a performance con, but it’s a factor in the product’s overall reception.

Each of these devices has clear strengths and some weaknesses. The best choice really depends on what you prioritize – absolute lightness? tried-and-true reliability? cutting-edge features? In the next section, we’ll sum up how each mouse fits different use cases and deliver our final verdict on which might reign supreme for various gamers.

Final Verdict: Which Mouse for Whom?

In this “ultimate showdown,” all three contenders are undeniably top-tier gaming mice. The truth is, none of them would be a “bad” choice – each can claim the title of best in certain categories. Rather than crown one single winner for everyone, it’s more useful to highlight which mouse is supreme for which type of user in 2025:

• For the Professional Competitor or Everyman Champion: The Logitech G Pro X Superlight 2 remains the gold standard for a no-nonsense competitive mouse. It’s the safe pick that delivers on all fronts: excellent comfort, very light weight (if not the lightest), rock-solid wireless, long battery, and a pedigree of reliability proven by years of esports dominance prosettings.net prosettings.net. If you’re someone who wants a plug-and-play workhorse – a mouse that you can trust at LAN events, in marathon ranked sessions, and in varied game genres – the Superlight 2 is hard to beat. It has the best balance of features and practically no weaknesses. As one review noted, it’s basically “the industry standard” now prosettings.net prosettings.net. Furthermore, it’s backed by Logitech’s strong support and readily available if you need a replacement. This mouse reigns supreme for versatility and widespread competitive use. It’s especially great for players who use a mix of palm/claw grip or those who just don’t want to think too much about their gear – they want it to work, feel comfortable, and get out of the way. The Superlight 2 does exactly that, acting like an extension of your hand for any FPS, MOBA, or even productivity tasks. It’s also a top recommendation if you have larger hands or simply never want to worry whether your mouse will perform – because it always will, with a decade of Logitech’s engineering behind it.
• For the Cutting-Edge Performance Seeker (the Tech Enthusiast/Precision Aimer): The Razer Viper V4 Pro stands out as the bleeding-edge tech leader. It’s the mouse for those who demand the absolute latest and greatest and aren’t afraid to pay for it. With 8000 Hz wireless polling, Razer’s finest Focus Pro sensor, and the crisp Gen-3 (or Gen-4) optical switches, the V4 Pro is all about pushing the limits of what a competitive mouse can do prosettings.net prosettings.net. It’s incredibly light and agile, nearly matching Finalmouse in weight while offering a sturdier build and more features. This mouse reigns supreme in pure spec-for-spec capability among mainstream brands. It’s ideal for players who identify as aim enthusiasts or hardware geeks – if you’re the type who is always tweaking settings, measuring latency, and striving for that extra 1% advantage, the Viper V4 Pro scratches that itch. It’s also the choice for many esports pros in 2025, evidenced by its massive uptake prosettings.net prosettings.net. Notably, if you favor a claw or fingertip grip and want something a tad more hand-filling than the Superlight, the Viper’s shape could be your holy grail – numerous pros who once stuck to Logitech have transitioned to the Viper V3/V4 shape for its comfort and control prosettings.net prosettings.net. The V4 Pro is also a great pick if you love customizing your setup: the synergy of Synapse’s options and the mouse’s hardware gives you unparalleled control over how it operates. One could say the Viper V4 Pro is 2025’s technical champion, the mouse that shows where gaming peripherals are headed. It’s not shy about its high-end nature – and if you want that Formula 1 engineering in your hand, Razer delivers it.
• For the Ultra-Lightweight Purist or Niche Aiming Specialist: The Finalmouse Ultralight X is in a league of its own, crafted for those who will settle for nothing but the lightest, fastest-feeling mouse on Earth. It reigns supreme in weight reduction and quickness, making it the top choice for players who prioritize flick shot speed and minimal inertia above all else finalmouse.com rtings.com. If you’re an aim trainer devotee or a Fortnite/Valorant prodigy who believes a lighter mouse will let you react and micro-adjust faster, the ULX was literally built for you. Its 30-gram-class weight, combined with the high polling and low click latency, gives an almost uncannily responsive feel – as if the mouse teleports with your intentions. It’s also perfect for those with very specific hand sizes or grip needs, thanks to the three size options; for example, if you have small hands, the ULX small might fit you better than any Logitech or Razer ever could. That said, choosing Finalmouse is a commitment. You have to be okay with the premium price and the quirks in build. It’s the mouse for the player who says, “I’ll do anything for performance gains”, even if that means handling a more delicate device and jumping through hoops to get it. Some pro aimers (especially in games like Fortnite or Apex) do swear by Finalmouse products for their ability to facilitate faster aiming movements – whether that’s placebo or reality is up to the user, but if you believe in the philosophy that lighter = better, the ULX is the embodiment of that. It’s also somewhat of a status symbol in the competitive community; using a Finalmouse signals you’re serious about your gear (and possibly that you’re an aim nerd, in the best way possible). Just be prepared to treat it gently and maintain it, as you would a finely-tuned race car.

Closing Thoughts: In 2025, all three mice reign supreme – but in different kingdoms. The Superlight 2 rules the realm of reliability and all-around excellence; it’s the champion trusted by pros across titles, from CS:GO to Overwatch, a true jack-of-all-trades that is masterful in its simplicity prosettings.net prosettings.net. The Viper V4 Pro rules the domain of innovation and cutting-edge performance; it’s the hotshot new contender pushing boundaries and setting records, perfect for those who always want the newest tech prosettings.net prosettings.net. And the Ultralight X rules the extreme frontier of weight and speed; it’s the choice at the very fringe of competitive optimization, catering to a niche but passionate crowd of performance extremists finalmouse.com rtings.com.

Which one is the “best” of the bunch? The honest answer: whichever one best aligns with your needs and philosophy as a gamer. If forced to pick an overall winner for most people, the Logitech G Pro X Superlight 2 arguably still holds the crown as the most well-rounded, tournament-proven mouse – the fact that over a quarter of pro FPS players still use a GPX variant speaks volumes prosettings.net prosettings.net. It delivers superb performance with minimal fuss, and now with its upgrades (optical switches, USB-C, higher polling) logitechg.com logitechg.com, it has no glaring weaknesses. It’s the safest recommendation to anyone asking “What gaming mouse should I get to perform at my best?”

However, for those who crave that slight edge or a different feel, the Viper V4 Pro could very well be the new king in waiting – many would argue it already is, given its adoption and specs. In the hands of a skilled player, the V4 Pro’s advantages (like insane polling and perfect sensor) can translate to incredible consistency and confidence in-game prosettings.net prosettings.net. As one reviewer concluded, “the Viper V3 Pro is the new benchmark” prosettings.net, and the V4 Pro only raises that bar higher.

And if you’re the type who’s willing to venture beyond the mainstream for ultimate performance, the Ultralight X offers an experience that’s hard to describe until you try it – it genuinely can make your mouse feel like a virtually weightless extension of your hand. For some, that’s the feeling of supremacy in aim.

Bottom Line: All three mice are winners, and each reigns supreme in its category – you won’t be held back by any of them. Your decision should come down to your personal priorities: Do you value universal comfort and proven track record (go Logitech) prosettings.net prosettings.net? Do you want the latest tech and a shape that many pros now favor (go Razer) prosettings.net prosettings.net? Or do you demand the lightest setup possible and are willing to accommodate a more exotic piece of gear (go Finalmouse) finalmouse.com rtings.com?

In the ultimate showdown of 2025, the real winner is you, the gamer, who has an unprecedented array of phenomenal mice to choose from. With any of these in hand, you’re equipped with a mouse that can genuinely help you play at your peak. Choose the one that feels right for you, and you’ll have a supreme weapon to bring into battle. Happy gaming!
