I personally prefer the PS4 for 4 reasons...
1. Sony made the playstation, ps2 and ps3, all of which (especially ps1 and ps2) have been absolutely godlike consoles
2. I would never buy a console thats main focal point is not gamin, microsoft stated that the XBox One would be focused on social networking and media streaming instead of just gaming... I have a PC, I don't need another one... and I don't like call of duty or FIFA, so other than Halo, XBox one has nothing to offer.
3. Common sense suggests I should go with the console that "got it right" the 1st time as opposed to the XBox that needed to be changed a lot just so people were willing to buy it. last minute changes on microsofts part means the console wasn't good and has now been rushed into what they hope will be a good console, PS4 on the other hand was already spot on.
4. XBox One's have already started going wrong... 'nuff said
As a fan off the XBox 360 I personally feel let down by the One. The console that at one point had me all excited now just makes me feel glad I went back to sony for my gaming fix.
