Mouse Recomendations for 19.5 x 9.5 hands

Hi all, I have been using my logitech g pro wireless for a while amogn other mouse which i cant seem to produce the same results with, but now its getting to a point where i'm maybe outlasting the shape on the GPW and i start to jolt the shape around a lot when aiming as opposed to a smooth guided aiming motion.

I'd like to recontinue my search for my "perfect" mouse, I have 19.5 x 9.5 hands. When gripping the GPW I tend to grip with top part of my thumb in like a relaxed pincer while my ring and little finger rest longways over and down the shell ( if anything my ring finger ever so slightly raised) with my middle and forefinger in a raised almost slanted claw like position.

Edit: Here is my mouse grip to help a bit more with suggestions: https://imgur.com/a/OHteWAW
