Think about how much the controller layout matters to you, the exclusive games you want, price for online membership, and other factors that will help you decide which is better suited for you.
Yeah, that thread that was posted above is good. Look at a list of exclusives and figure out what you're more interested in for each console. Personally I'm going to be getting an Xbox One because of Cuphead, Crackdown 3, Sunset Overdrive, and Halo V, not to mention all my 360 games.
