Mouse recommendations for 20x10cm pincer claw?

Hello,
My XM1r has started randomly disconnecting after ~3–4 years, so I’m looking for a new mouse.

Hand size: ~20 × 10 cm
Grip: pincer claw, (index & middle fingertips close to the top of the mouse)
Games: CS and Marvel Rivals
Budget: not a problem

Mouse history: Corsair Harpoon → G403 → XM1r

The XM1r feels the most natural so far, and I’m pretty sure I like it. I do perform better with it than the G403, and its shape seems to work well for pincer claw. That said, I don’t have a ton of mouse experience, so I’m not completely sure whether I’d benefit from something a bit larger, or if the XM’s size is already spot on. Would ambi shapes generally be better for this grip than ergos?

Mice I’ve been looking at:

• Maya X
• XM2Wv2
• Viper V3 Pro
• Pulsar X3
• Terra
• Santali S1-O
• DeathAdder V4 Pro

The Santali S1-O caught my eye since EloShapes lists it as very similar to the XM, but ~13g lighter than the XM2W and cheaper. It seems like a good experiment, though I’d also be happy sticking with the XM if it’s already considered a “perfect” pincer mouse.

Would appreciate any advice on finding a perfect pincer claw mouse with my hand size. Thanks!
