You can't go wrong with either, assuming price is no issue. PErsonally, I'd recommend the PS4, though. Cheaper, better exclusives, better online benefits, and better multiplatform games.
At least that's what it looks like.
Price - 400 vs 500. PS4 Wins
Hardware - PS4 (stronger system, more options)
Multiplats - PS4 has better hardware architecture.
Online - PS4 (cheaper, more benefits)
Exclusives - Uncharted, God of War, etc vs Gears and Halo. Tie
The only thing that might be an Xbox One bonus OVER the PS4 is the exclusive games. If you love Halo, Gears, and Forza a lot, then you can't go wrong with an Xbone. I personally think the PS brand has more exclusives, as well as more variety and quality.
But the difference between the two is so small that it's really not a decision. go with whichever you think has better exclusive games.
