I'm an avid Android user, still rocking my Nexus 4, but alas, the hardware doesn't perform the way it used to and has earned its retirement. The Nexus 6P and 5X are my top two choices for a new phone because they present the biggest step forward in pure Android evolution. The 5X is more economical, but the increased storage capacity, RAM, and screen size makes the Nexus 6P the most worthy of prizes.
