It really comes down to what your friends have at this point. There's positives and negatives for both, and I'll admit ps4 has a lead in sales. I bought my x1 because I prefer the Xbox controller to the ps, and I only played with a few of my friends who all purchased the x1. If they had bought the ps4 I probably would've gone with that. Yes I have friends that have the ps and they would give me crap for buying the x1, but now I give them crap for not being able to play. These console warriors are just children. Research the games, what your friends play on, and which controller you prefer. 900 vs 1080 doesn't make a huge difference unless you have excellent vision or a giant tv. I have a buddy who complains when we watch something on my tv because the x1 isn't 1080 native. I honestly can't tell them difference, but he's really good at it. My other buddy has both systems and he uses the ps4 only for single player games. He likes the graphics but wants to play with me (yes, I actually convinced him to buy one just so we could play mcc together, an old tradition we had etc etc). Tl;Dr friends, games, controller, graphics. You decide what you want from there.
