It's really up to what games you want to play; both systems are equal in terms of power IMO and each has a set of exclusives that will make them must own. Personally I'm going with a Xbox One first then getting the PS4. Also I'd take Kain's post with a grain of salt he's shown quite a bit of biased toward Sony as evident in that last post.
If I where you Hybrid Gojira I'd research what each system has to offer then make your decision from there. Yes MS had a bunch of crappy policies in place originally but they've changed that quite a bit since the system was annouced.
