3 multiplatform games are better on Xbox one. Counting 5 tied. Every other game (hundreds by now?) are better on PS4 (at least according to these analyses).
I was just mentioning it to the guy about to buy the worse hardware to play Madden (a multiplatform game). If the prices are the same might as well get the better hardware to play the better versions, although I think xbox is cheaper now than PS4.
