It's an easy choice. Get what your friends have. Let's say you get a PS4, and none of your friends have a PS4, you're going to be bored. If you get an Xbox One and most of your friends have one, you'll have fun because you'll have people to play with. No one likes playing solo.
For me it really depends on which console my friends have, because playing with them is honestly the most important part for me. I can bear some small things if I get to play with all my friends. Also, I move my console around a lot, so I really wish I had a PS4. It's much smaller, and lighter than the Xbox One.
