I also have a pixel 6 and it is fine for me as well. It runs everything I need without issue. The only issue I am seeing is that lately, and only occasionally, after the screen shuts off completely and the always on display turns off, the screen won't come back on at all unless I press the button on the side. It used to come on if I looked at it or turned it over, now it only does that sometimes. I think it is getting slower as well, but that could just be psychological.
I don't know if I should just get the 8 pro, or wait for the 9 next week. Either one would be an upgrade for sure.
