Exclusives matter to you? Better graphics? And according to me, better controller. Then go with PS4. I bought both last year, but traded my Xbone in for games in February after trying the Titanfall beta and seeing that it was terrible (for me).
I'm looking forward to Bloodborne, No Mans Sky, Guilty Gear Xrd, Hotline Miami 2, Uncharted, hopefully a Last of Us sequel and many more exclusives. But I also chose to only have a PS4 because there was nothing besides Halo that I was looking forward to on Xbone. And sadly, it seems that 343 has screwed that up.
Hard to go wrong when buying a system that has 2 times as many sales as the other two as well. It makes it more likely to get better content and games as well as possible exclusive content like Destiny has. Companies don't want to miss out on the PS4 audience.
