All the Ponies (sony fanboys) will jump up and down screaming graphics and running smoother. I have not noticed any visible difference between the two systems. At all. I have both. In fact, the Xbone tends to get shit done faster, and contains WAYYYYYYY more features. So it boils down to games. PS4 - No Man's Sky, but owned by a pathetic company who yet again, ruined Spider-Man Xbone - Halo Series, and full support from Microsoft, one of the most successful software companies since ever. I'm biased towards the XBone, obviously.
