Kudos need to go Samsung and LG for really stepping up their game in the past few years, going from mediocre cameras to best-in-class units. But it's the Nexus 5X (and thus the Nexus 6P) that win this battle. The new Nexus phones may not have the most pixels to work with, but the big sensor with relatively huge pixels, collecting light through a nice bright aperture, but the photos they're producing are positively phenomenal.
