Comes down to you and what YOU want. The masses will have their opinion on which one is better, but it all depends on what you want.
If you want an XBOX ONE, buy a XBOX ONE.
If you want a PS4, buy a PS4.
If you don't wanna miss out on the exclusives both consoles has to offer and you can afford it, buy both.
It's completely up to you. For me personally, I'm getting my PS4 first. =)
