Yeah a online poll is pointless as the fanboy part is still rabid. I would love to have a actual survey of people who are confirmed to have both.
Controller: Xbox one. The Ps4 is much improved and the xbox one is slightly worse than the 360 but the location of the sticks still put the xbox on top for me.
Hardware: If we want to go based on pure specs PS4, if you want to go on the way its been used its a tie maybe a tick in the xbox's direction.
Game Library: If you want to look at actual available games I would have to say Xbox, to me another Tie.
UI: At first glance the Sony is simpler but could get worse as you get more games. Xbox was a tad more confusing(especially if your not use to windows 8). Really I don't have a real preferce unless you bring Kinect in to the fold then its easier but I don't have the PS camera so i don't know if that really makes it better
Online: I would give xbox a slight edge as it seems to have better bandwidth. It seems like PS downloads are painfully slow. Past that they are about the same.
Overall: I would have to Xbox but really it comes back to the controller. I play the PS more online but purely because friends went with PS, but if I am not playing online I will play Xbox more but thats also because I have more games I haven't finished on the Xbox.
