Get an Xbox One.
To be honest, all depends on how many friends you have that play whatever console, because don't get me wrong, both consoles games get boring when you're playing by yourself.
Ps4, Made for Streaming
Xbox One, Made for gaming / Downside: Everything is an App. Which is pretty stupid imo.
Depends. If you're already invested in one or the other on the last gen consoles, stick with the same. At the moment, I like a lot about the PS4, but without friends on it, I play Xbox One far more.
