For the most part, it comes down to which controller you find more comfortable, what your mates play on, and which exclusives you like better. PS4 is technically better when it comes to hardware, but it is so small and negligible that it really doesn't matter. For me, I have no interest whatsoever in Halo since after Halo 3, no interest in Gears of War, or pretty much any Xbone exclusive. PS4 so far has been absolutely great, with exclusives I love (Such as Bloodborne, Last of Us, etc). I also very much enjoy the simplistic yet sharp menu screen. I used to have a 360 and PS3, and Xbox's UI menu was just so bloody clunky looking and filled with advertisements (Not sure if this is still an issue with Xbone). Again, this is just my opinion, of what I enjoy.
