I've got both so have a pretty unbiased opinion.
Xbox One feels like more of an entertainment system. The apps, friend feeds, etc... make it feel a lot more community based than the playstation and feels a bit more user friendly.
Whereas the Playstation is a gaming console. It still has a few apps, etc... But nowhere near as good as the xbox, as the main focus is soley based around playing games. The PS technically has better graphics, but nothing has really come out to push them to the max anyway, so you cant really notice any difference between the 2 when youre actually playing. But i prefer the PS exclusives.
It's completely pointless asking that question on a forum, as everyone will just give their biased opinion on whatever they have. In the long run it basically just comes down to "Which controller do you prefer to use?" & "Which exclusives do you want to play?". Simple as that.
