I have the G502, G602, G600, Performance MX, and MX Master. For gaming, I'd have to hand it to the G502, hands down. Although if you must go wireless, the G602 in performance mode is fantastic, as are its ergonomics. The Performance MX and MX Master I would not suggest for gaming, although for work tasks the MX Master can't be beat. The G600 really only excels at MMOs, I haven't really used it for much else (although it will probably be my new recording/DAW mouse once my G500 dies).
