I think it really is down to what games you are interested in. For me the only game I want for the One is the Halo Collection at the moment, I have others but havent found them worth an entire console. As for the console itself and the OS I will always recommend PS4 over Xbox One, as I've said before I have had a terrible experience with my Xbox and do not like it one bit whereas my PS4s OS might be a bit spartan but it works just fine.
It also depends on how interested you are in multiplayer gaming and where your other friends are. PS4 seems to be the place for online if you want to meet up with other NE people but of course if you have other friends that have or will get an Xbox One then that could easily be another reason to go with that.
