The only times I heard about Google being good at hardware were “trust me” anecdotal and unverifiable stories about DC equipment. At best this says Google cares about the HW they use not the HW they sell to an end user.
I've had the Pixel 2, 3, 4, 5, 6, 6a and 8 Pro and each has been excellent. I've had no hardware problems with any of them.
Google themselves acknowledged their phone have issue in leaked document.

Beside this recent issue with tensor, everyone know that pixel phone don't hold up. They always break one way or another, which was barely acceptable when they were cheap.
Your collection of pixel either say you got many defect or you switched so frequently you didn't have time to see them appear.
