As far as the ps4 goes I havent really had any big problems with it aside from the controller battery life. Although as far as the x1 goes all of those problems can be fixed with patches.
To be honest I play the X1 more than the PS4 right now, but that is because of how many friends i have that play it. If that wasn't a factor Im sure i would be playing both the same. amount. If I had to give advice on which to get I would have to say to look at what your friends are getting, if that isn't a issue than which one has the exclusives that interest you? Right now with all the announcements both seem to be getting some heavy hitters in the future. Off the top of my head
X1:
Quantum Break (Great looking game that combines Alan Wake story telling with Max Payne Cinematics
TitanFall Turning out to be the most anticipated game of next gen
Halo 5 One of the defining games for Xbox
Project Spark A game for those with an imagination big enough to create their own game
Sunset Overdrive Not too much can be said about this other than it reminds me alot of Team Fortress
PS4
Infamous Second Son: If you havent played the previous games you have been missing out, defintitely looks to fill out that gaping hole where a super powered hero game belongs
The Order: 1886 looks to be an awesome steampunkish shooter
Uncharted 4 One of the series that makes the Playstation what it is, fantastic series
Driveclub There to help you with that racing itch, its visuals seem to be nothing short of fantastic
