I own a 5x. The camera will be the primary reason I upgrade before I really need to. Its mostly decent but occasionally bad: Out of focus (or incorrect focal point), extremely poor in low light, occasionally crashes (not doing anything fancy here). I think the phone overall is good, and I can't imagine using non-vanilla android. But prior to the Pixel announcement (and after owning this and last gen's Nexus) I'd started considering giving the iPhone a try based solely on the camera.
