I got a Pixel 4 XL on launch day and love it. Come at me, bro.
It's not perfect by any means, but it's a great phone. It's my relatively uninformed opinion, but many of the complaints are way overblown. The battery, for example, is fantastic for me. I've experienced zero issues with the face unlock or gestures and the speed of the new Assistant is insane. A feature that isn't getting much love is the new live-captioning. Just a game-changer for me as I can now watch videos without turning up the volume or wearing headphones. I can't believe how well it works already.
I just need a case asap and the glass back is freaking me out.
I have to point out how easy it is to upgrade from Pixel to Pixel. The entire process took about 20 minutes and worked flawlessly.
