You probably already read about the excellent camera in the Pixel/Pixel XL. I made some tests for myself and was quite impressed.
A just for fun try with a Samsung WB251F digital compact camera and the Pixel XL shockingly didn't turn out good for the dedicated Samsung camera. Sure a normal camera is still better, with the 18x zoom alone, but in terms of real colors and details I was baffled how a smartphone camera can be better.
