I suggest these little guys:

Which grip are you?

I have a Logitech G604 and it works flawlessly with piper to setup the extra buttons.

I can recommend Logitech G102/203. It's smaller in size, so it's comfortable mostly for claw or fingertip grip users.

You get what you pay for (if you do your research, like you are). Personally I'm willing to spend a bit more on peripherals, I spend a looot of time driving a mouse. I'll second the logitech recommendations and point out my 4 yr old MX Master 2 is still getting weeks on a charge, beat to hell, but still fully functional and better at gaming than any gaming mouse I ever had (looking at you razor, but if I look at you you'll die, like you did). If you do go logi, check out logiops, realy useful.

I have a Corsair and it doesn't always play nice with my AliExpress kvm. Works fine after a re-plug.

I would avoid Razer mice, I got two Mamba Elites and both of their mouse wheels are broken/bugged (if you scroll in one direction it scrolls back and forth, or scrolls twice when you want to scroll once). My sister got a Deathadder Elite and its mouse wheel is completely broken.

I picked up an Anker vertical mouse for like $12 from a used PC parts store and it's been working just as well in my opinion, pretty comfortable and still has a working scroll wheel.

Of course you could also buy a drawing tablet and set it to mouse/relative mode and play with that, which I did for a while, but the lack of a scroll wheel stops you from playing some games.
