If we Had to Choose?
In competitive FPS games, hardware performance is critical. In all honesty any of the mice above will perform well in during fps game play. However, if you had to make me choose I would go with the Razer DeathAdder Elite, it’s a great mouse in terms of quality and accuracy… However, I could be slightly biased having owned one for 5 years (which has never let me down). If you’re heading for the pro league then the Zowie EC2-A is a good choice.
If you’re on a super tight budget checkout the Redragon M711 Cobra which is a great mouse for the price but don’t expect Razer, Zowie or Logitech build quality. If you don’t want cable all over your desk than check out the Logitech G903 LIGHTSPEED, it’s an amazing mouse and is best used with the mouse pad, it performed so well it was not noticeable the mouse was wireless.
