Both my wife and I had these and, despite initial promise, they behaved horribly. One particular issue was overheating and shutting down. IIRC the boot loop issue, when it eventually struck, was worked around by a hack to disable two CPU cores.
Due to this and the poor performance of Wear OS (or was it still Android Wear at that time?) we switched to iPhones.
I note that the reason I first got a 6P was because my 6 completely died one day and a 6P was the only available insurance replacement.
Despite all this, I'm likely to by the Pixel 8 and Pixel Watch 2 to replace my iPhone 8 plus.
