Having played both the PS4 and X1, I have this to say:
The graphics of both are pretty much the same and are not much better than the graphics of later xbox 360 games like GTA V.
The X1 is a multimedia device and is quite unique in that regard. The PS4 is not.
The controller of the PS4 is as BAD as the rest of the playstation controllers. The sticks are too loose and are placed in the same awkward parallel position: this makes it almost impossible to play first person shooting games with the level of accuracy you have on xbox controllers.
The PS4 is simply the PS3 with marginally better graphics. PC graphics of 3-4 years ago are better/same than both systems.
