FK1

It depends on the type of gaming mouse. When it comes to the mice being used for CS, the main difference is sensor quality. I mean, I got my Zowie FK1 sometime around 2016-17 or so, so the tech may have improved since then for regular mice, but back then, gaming mice just had way better sensors. And then, you also get to choose the actual shape of the mouse (something ergonomic vs the classic microsoft mouse shape for example). When it comes to MMO/MOBA mice, you also get tons of additional buttons on the mouse. As it has been pointed out, weight and switches are also a factor, but I actually never gave it too much thought. When I got my Zowie I only really cared about having a top tier sensor and a classic microsoft mouse shape.

If it's longevity you're after, I've been on the Zowie FK1 since the collab with Neo (I'm thinking it was around 2014), and I still use it till this day. Still fully functional. I'm gonna guess that FK1 is not produced anymore, but maybe FK2 is.

I like the Zowie Fk1. I also have big hands(21cm) and ralaxed claw to claw.

Xm2 / X2 / FK2-DW (i’d wait for fk1 here though w ur handsize, so maybe save up?) Those are my fav mice for claw, i particularly like the FK. I also enjoyed some clones, R5 ultra felt nice (very small, ULX clone) but it was too light for me at 38g. The superlight / superlight shape (atk A9 ultra or pro max) is quite versatile, could do you solid. Aj159 Apex (slightly bigger OP1, it’s decent, but normal op1 felt more premium) All mice i’ve mentioned have solid clones & the xm2w should be within your budget.

fk1 comes to mind with your handsize, i have slightly bigger hands and use the fk2-dw perfectly aswell though, so you may want to consider that too! ”Ergo for claw grip” is pretty much FK in a nutshell, can recommend.

ZOWIE FK-1 maybe? It's their biggest one for large hands.

only mice i can think of big enough is the final mouse classic (large size) m, zowie fk1/fk1 +, or S1 at the cost of weight though and the s1 has a larger hump which could hinder finger mobility, then there's the pwnage storm breaker max which is a lightweight ergo but i've used the grip you're using aswell and ambi imo is just better for it
