Nexus 6P - the best Android device ever made
If there was any doubt about the Nexus 6P being the best Android phone ever produced (as in the best overall package - performance, battery, build quality, speakers, software, camera, etc), this newer MHC19l build will clear those doubts. Not only its performance has improved due to numerous changes in the framework + Kernel, it proves the so much criticised Snapdragon 810 runs beautifully and cold as fuck when the software implementation is right. An unfuckable Android version without OEM/carrier shit or ridiculous UI fuck ups, with proper tuning (Marshmallow really did up its game when setting up different tasks to sets of cpus as I explained earlier).
So yeah, you can cry all you want about your precious little OEM'ed device, the Nexus 6P is the closest thing to a perfect device, and there's no other offering a package like this. The only thing I personally change would be having smaller display.
