First Impressions
When I first opened both boxes and moved from setup to scrims, the split was obvious fast. The Viper V3 Pro felt instantly neutral in hand at 54g, while the Superlight 2 DEX at 60g felt more anchored and palm-friendly, especially for longer sessions where wrist stability matters. That six-gram gap sounds tiny on paper, but in fast tracking drills it changes how hard you need to stop flicks cleanly.
Reddit’s current recommendation pattern lines up with that first feel: these two keep showing up as default answers for competitive FPS buyers, usually with “shape first, then brand” advice from r/MouseReview and build threads. I saw that trend in recent discussions where users narrowed final picks to Superlight 2, Viper V3 Pro, and a few niche alternatives.

What Worked
Performance is elite on both, but they win in different ways. Logitech’s DEX gives you a safer right-hand ergonomic shell with high-end internals, while Razer gives you lower weight and a shape that adapts better across claw and fingertip styles. In practical FPS use, DEX gave steadier micro-correction in hold angles, while Viper made repeated snap shots feel less fatiguing by round eight.
Core spec and feel comparison
| Feature | Logitech G Pro X Superlight 2 DEX | Razer Viper V3 Pro | What It Means in Practice |
|---|---|---|---|
| Weight | 60g | 54g (black) / 55g (white) | Viper needs less force for rapid direction changes; DEX feels more planted for controlled tracking. |
| Sensor class | HERO 2, up to 44K DPI | Focus Pro 35K Gen-2, up to 35K DPI | Both are beyond practical DPI use; shape and click feel matter more than headline max DPI. |
| Polling support | Up to 8kHz | Up to 8kHz | Competitive latency is top-tier on both, but battery drops faster at higher polling. |
| Battery claim | Up to 95 hours | Up to 95h @1000Hz, 17h @8000Hz | You can keep 1kHz daily and toggle higher polling only for ranked sessions. |
| Buttons | 5 | 8 programmable controls | Viper gives more binding flexibility without MMO-level clutter. |

Software-wise, both apps are powerful enough for serious tuning. Logitech G HUB gives solid profile control and is easy once profiles are set. Synapse has deeper polling and battery behavior visibility, which helped when dialing down from 8kHz to 2kHz for mixed play and work calls. This is where competitive players gain consistency: set one profile for ranked, one for everything else, and stop touching settings mid-week.
What Didn’t
No perfect mouse exists, and Reddit is blunt about it. DEX is expensive for a five-button, minimal-feature mouse unless you specifically want that shape, and some users still complain Logitech side-button feel can be hit or miss over time. On the Razer side, there are user-reported quality worries around long-term reliability in broader Razer lines, plus Synapse still isn’t everyone’s favorite background app.
The bigger practical issue is battery tradeoff at high polling. Razer explicitly lists the drop from 95h at 1000Hz to 17h at 8000Hz, which is excellent transparency and also a warning label. If you leave max polling on full-time, you are charging far more often than most buyers expect. The mouse is fast, not magic.
A second friction point is that both options are “pure performance” mice with limited extras. If you want infinite scroll, lots of side buttons, or productivity-first features, these are the wrong tools. Buying either for MMO-heavy binds is like bringing a race kart to a grocery run.
Pricing Reality Check
Street pricing in 2026 is aggressive, and this changes the recommendation more than specs do.
2026 pricing snapshot (US)

| Razer Viper V3 Pro (Best Buy white listing) | $114.99 sale seen | $159.99 comp value shown | 2026-02-17 | https://www.bestbuy.com/site/razer-viper-v3-pro-ultra-lightweight-wireless-optical-gaming-mouse-with-95-hour-battery-life-white/6576244.p | Deal pricing can make Viper the easy pick for most competitive buyers. |
Reality check: both brands run frequent discounts, and prices shift by colorway. Check black vs white before checkout; that alone can save $15 to $25.
Who Should Pick Which
Pick Logitech G Pro X Superlight 2 DEX if your top priority is right-hand ergonomic control and stable long-session comfort. If your grip is palm or relaxed claw and you play tactical shooters where controlled tracking beats hyperactive flicking, DEX still earns its premium.
Choose Razer Viper V3 Pro if you want the strongest blend of pro-level speed and current value. For mixed claw/fingertip players who rotate between CS2, Valorant, Apex, and daily desktop use, it’s easier to recommend right now because it is lighter and often cheaper while staying top-tier in latency and sensor behavior.
Buy if: you want a serious FPS mouse and will actually tune polling and profiles once.
Don’t buy if: you need lots of side buttons, office-first ergonomics, or zero-software setup forever.
Clear alternative: Logitech G502 X if you want more buttons and broader all-purpose utility over featherweight esports focus.
