If you are serious into FPS, I would only consider these 3 mice. I am FPS siao so my selection on mice is rather limited based on my playing style.
1) Razer DeathAdder Elite
2) Steelseries Rival 310
3) Logitech G403
Generally, for FPS, keep your mouse as light as possible.
The above 3 mice are proven and used by many e-sports gamers alike.
I would rather stick to proven designs then try out new mouse. Sometimes, new sensors in new mice may frustrate you when you play FPS.
So IMHO, keep it simple and choose between the 3 mice above is what I would recommend.
