OP1 8k

Ergo: EC1-C. Fits my hand like a glove and is perfect for palm grip. I also love the soft clicks even though it does add a small amount of travel distance. Looking forward to trying the EC1-DW when the glossy coatings release. Symmetrical: OP1 8K v1. The slimmer design allows me to grab the mouse with my ring and pinky finger being straightened out, which is another technique I use to control my mice. It also has a noticeably more responsive click latency compared to my EC1. Polling rate doesn’t matter to me, but it’s nice knowing that it’s future-proof with 8Khz capability and swappable switches without soldering.

Endgame Gear makes and sell the best performing mice on the market. Razer also sells a wired version of the Deathadder V3 giving you 8K polling and 8K click latency across all sensor polling rates. If you're in Europe, you can probably buy some old Zowie wired mice through something like Max Gaming. You can buy them in NA through the same site, but the shipping is gonna be stupidly expensive.

I use both Endgame Gear and Zowie. I can't tell the difference between the sensors at all. I only notice that click latency being a bit faster on my OP1 8K, but that's mainly because it's a smaller mouse with less travel distance. I do think Endgame Gear is the better choice still as it gives you options like switching mouse click switches without any sodering needed while having mouse feet with holes so you can access the screws without taking the feet off. That's on top of having the best measured performance, 8K polling, and consistent 8K click latency regardless of sensor polling rate.

Op1 8K or the wireless 4K edition with brown silent switches sold in a separate pack is the only thing I can come up with. You can barely hear it and it feels like a brown mechanical switch you'd use on a keyboard.
