Razer Viper V3 Pro vs Razer DeathAdder V4 Pro

Both are right-handed, wireless, 8K-polling Razer esports mice, so the choice comes down to shape and sensor ceiling. The Viper V3 Pro is a low, flat, symmetrical-feeling shell at about 55 g with a proven 35K sensor and a large base of owner feedback. The DeathAdder V4 Pro is a taller ergonomic hump at about 56 g with a newer 45K sensor, an optical scroll wheel and longer rated battery life, but far fewer owner ratings. Buy the Viper if you claw or fingertip grip and want the shape pros have used for years. Buy the DeathAdder if you palm or relaxed-claw and want the newest sensor and scroll wheel.

• Choose the Viper V3 Pro if you prefer a low, flat profile for claw or fingertip grip and want a mouse with a long track record among esports players.
• Choose the DeathAdder V4 Pro if you palm or relaxed-claw and want the taller ergonomic hump, the 45K sensor and the optical scroll wheel.
