The Pixel is the far superior product as far as I am concerned: Faster, more stable, no bloatware and the best camera around.
But, and this might be a big but for some, if you need repairs or service outside of insurance you are SOL. There's not a lot of companies doing Pixel repairs and if they do the parts are insanely expensive. I needed a screen replace and it cost almost as much as the phone itself in parts and labour. And the end result is a screen that gets dirtier and a non-functioning fingerprint sensor. Not optimal.
Awesome phone, but pray you do not need service.
