Which should you buy?

• ▸Pulsar X2V2 is the lighter mouse (53 g vs 54 g) — the edge for flick-heavy aim, fast wrist play, and less fatigue over long sessions.
• ▸Razer Viper V3 Pro polls up to 8KHz — but headline polling rate barely decides a mouse. 1000 Hz is the floor and 2000 Hz the sweet spot; the gain halves at every step above (2K→4K ≈ 0.25 ms, 4K→8K ≈ 0.06 ms), and 4K/8K cost real CPU and wireless battery. Pick on shape and weight, not the Hz number.
• ▸Both sit in the same price class (Premium), so cost won't decide it — grip and shape will.
• ▸Focus Pro 35K and PAW3395 are both flawless modern sensors — tracking is identical for any real input, and the DPI/IPS numbers they differ on are ceilings no hand reaches. The sensor won't decide this; pick on shape and weight.
• ▸Razer Viper V3 Pro edges the Pulsar X2V2 on our measured best-built composite (98 vs 83/100) — independent click latency, sensor integrity, build/QC, weight and polling-link, scored price-aside. It grades engineering quality, not win-rate: the higher number means fewer measurable compromises, not that it aims for you.
• ▸Razer Viper V3 Pro lasts noticeably longer between charges — 95 hr vs 70 hr at 1000 Hz (4K/8K polling and RGB cut both sharply). Not an aim factor, just fewer charge cables in your week.
