Surprisingly I'm enjoying the xbox one more , although that might be more to do with the fact xbone has more games to play. There's pros and cons to each, I prefer the ds4 over the xbones controller, I prefer the xbones UI over the ps4's etc.
It's definately the best looking game atm, I thought kz looked really good, but after playing ryse for a bit I can say it looks quite a bit better then KZ. Although KZ is much more open ended while ryse is very linear. Still though ryse is simply breathtaking
