What is the very best controller for android gaming?

[AC Question]

Some ideas of controllers are xbox one/360, PS3/4 and bluetooth controllers designed for android devices. I want to find out which is the best controllers in these factors, 1. plug and play 'will alot of button mapping and apps needed to setup the controller; 2. power consumption 'how much power do they consume when they're connected of the phone or do they use their own battery' 3. Functionality 'how well do the controllers perform'
