Specifically I wanted to ask about chinkshit mice, I hear they are good and cheap. Haven't seen any of the most talked about models in store listing in my country. But maybe I'll get some recommendations

Currently using pic-related and I just bought last year as a cheap gaming / work mouse; it uses batteries and can do BT and 2,4G and I'm surprised how good it is.
Perspective; previous mouse was a Zowie EC3, still have it and it's utter dogshit in comparison. Zowie kept using shittier and shittier ABS for their shells over the years, so the 1,5 year old EC3 is all shinny and gets sticky after 15 minutes of use.
Still have the original FK1 with the yellow wheel. It sits in my office is like decade old and it's not even close to the level of shine the EC3 got. I also used the S2 for 2 years and that one is also less degraded, albeit more than the old FK1.

So questions:
- which of the chink mice is the most sshine resistant and I guess POM or PBT is too much to ask?
- are there any good ones that can use AAA bats and do BT?
- I consider 4 and 8K polling a meme, am I wrong?
- from what I've seen most chink mice use a symmetrical Zowie-like design, are there any ergo ones, but on the shorter side (wide is actually good for me)?
- the fuck is everyone shitting themselves over mouse weight? Don't care for that as I'm more accurate with the Razer with the AAA bat than the significantly lighter EC3, but still very curious.
