The Corsair M65 RGB Elite is a very similarly performing mouse to the Razer DeathAdder V2. They both have outstanding performance, but the DeathAdder V2 has a slightly higher max CPI, a lower click latency, and a lower lift-off distance. The Corsair is better for claw grip if you have small hands, but the V2 is better in both palm and claw grip for people with very large hands. Finally, the V2 has a much less stiff and rigid cable, which is great.
