I've use every single pixel from the Nexus line to the pixel to the 6, and the reason I skipped 7 is that the camera bar on the 6 is soo annoying.
It makes the phone 'negatively compatible with wireless charging, that is to say, when I put it on the phone spot in my car, it makes just enough contact with the wireless charger to go in and out of barely-in-range, causing my phone to heat up and lose battery charge.
