I would definitely pick the 5X 32GB because it's not much bigger than my aging G2. I would love to move to a Nexus because of the great development community.
Nexus 6P for me! That screen, that Camera and that smokin sexy body. Anything else is just lame. Marshmallow on point with that back Nexus Imprint? GIMME GIMME GIMME....Replace my Note 3!!!!
