Xbox rules.
Enough said

On a more serious note. I think everyone grew up with playstation and loved it before xbox v1 came out. Sony made one of the worst business mistakes ever, which in my view was releasing the ps3 near a year after the 360 (Sony owned the gaming sector!). This in turn led to a large proportion of gamers moved to the 360 as it was next gen. Would MS still be on par with Sony if the ps3 was released earlier?
I can still remember turning on my xbox 360 for the first time and seeing the magnificent wonder on the screen of which my eyes had not bestowed upon before.
However, it feels more now in this day and age as market gimmicks and pr polishing. I mean seriously, how many frigging versions of the xbox 360 do you need??
However, getting back to the op's question...xbox one as I am nicely settled with the 360now. Xbox live is superior service compared to the sony network. Kinect is totally awesome.
Please don't think, I am a xbox fan boy lol. Like I said, I have grew up my earlier years with playstation, even had ps3 for a few years with my 360, but the blueray drive went.
I would honestly say, I would had been in love with the ps3 if it had came out before the 360, but it didn't.
I think hardware terms wise, the human eye is not going to see much different between the one and ps4, so I wouldn't worry about it

I would stick to what you like

Thanks
