I have to recommend the G900. It's not the mouse comfortable mouse for claw grips IMO, but it's so responsive and
the wireless literally responds faster than a lot of wired mice. Also, the DPI buttons are nice and easy to press on the fly, you don't have to hunt for them.
I used to use a G9x, which is mouse nirvana but not made anymore, and also own a G502 and a Corsair M65 Pro. I can't stand the G502 - I don't like the grip, the side buttons feel like ass, it feels much cheaper than my G900 and M65 Pro.
The M65 Pro would be my go-to if I didn't own the G900. It's super comfortable IMO for both palm and claw grip, all aluminum construction so if feels nicely built, has adjustable weights, and I really like the side button placement and "sniper" button. Only complaint is that the DPI switches are somewhat annoying to reach in a hurry.
