Click latency has nothing to do with the switch type. Zowie just has somewhat bad firmware in that respect. Some day they will probably fix the firmware and release a new version of the mouse. I'm pretty sure Zowie can only make 1 change to the mouse at a time though. They don't seem capable of fixing multiple issues at once.
I know about that. But when someone wants to show that they're better than Zowie, they should mention omron switches. Cuz Zowie is the only major brand that uses huano for M1 and M2.
