Which should you buy?

• ▸Endgame Gear OP1 8K v2 is the lighter mouse (49.5 g vs 54 g) — the edge for flick-heavy aim, fast wrist play, and less fatigue over long sessions.
• ▸Endgame Gear OP1 8K v2 is the more affordable class — Value vs Premium — so it's the value pick if the shape suits your hand. Street prices move; the live price is on the buy link.
• ▸PAW3950 and Focus Pro 35K 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.
• ▸On our measured best-built composite — independent click latency, sensor integrity, build/QC, weight and polling-link, scored price-aside — they're effectively level (99 vs 98/100). Both are flawlessly built; the choice is shape and weight, not engineering.
• ▸Endgame Gear OP1 8K v2 is wired, so there's no battery to manage (or charge) — the trade is the cable; the wireless one trades a recharge for no cord.
