I'm currently shopping for a new mouse and I'm split between two Logitech products: the G502 (Proteus Core) and the G600. I really like the aesthetics of the G600 as well as the 12 side buttons it has, but I'm worried that it might not precise enough/too laggy for FPS games. I did some research, but before making my mind, I'd like to hear (or read I suppose) what you guys think.
