Pixel 3A. Constant bugs, camera would stop working or had a long delay starting up, system would randomly stop responding, constant crashes, lock screen would bug out preventing you from unlocking the phone. Dialer would bug out preventing you from answering the phone. Random reboots. Screen scratched really easily.
Phone crapped out about a month before warranty expired, wouldn't boot any more. Luckily, it was still in warranty and they returned the full price.
I've read a lot of reviews before buying, and that was my expectation as well. I had a Nexus 5 before and it was a great phone.
Maybe I got a lemon that had some hardware fault, I don't know. I've been wanting to get a newer Pixel just for GrapheneOS, but that experience was so bad, I'm having a lot of doubts
