Hey, I've had the Pixel 6 for several months now.
It's true that there were a lot of problems in the beginning, but they got less and less with software patches.
I have experienced it myself and now even have android 13 on it. Everything seems to run +- cleanly now.

What is to be criticised, which is probably due to the hardware, is the battery life. Depending on how often you use it, it only lasts 6-8 hours. It could also be that I have too many apps running in the background.
