Re: X Box One or PS4
As with all these things, the single most important factor in this choice should be what your best friends get. You can play online together, you can share games, this should be more important than anything else. Regardless of what the crazed fanatics say, both of these consoles are going to provide the same experience to a very large extent.
If the choice of your friends isn't an important factor, I'd go with the PS4. It's a hundred bucks cheaper and Sony has provided much better exclusive content for their system than Microsoft in recent years.
