Think it's highly dependent on personal taste - only thing I was interested in on XOne side are Quantum Break and Forza 5 (later mainly cause I'm curious how that "human AI" thingy works). Not much more on PS4 either, tbh.
As always, 3rd parties are source of games I usually like the most, so there's not much difference there (unless Deep Down really is exclusive, being THE game I'm most interested in among all next-gen offerings revealed so far)
