I actually have both.. the xb1 version looks fine to me... and is more fun that BF4 (that is frustratingly horrible) - They have stated though that a planned update later may push the xb1 version to 900p instead of 792p
but even on my old PC I can still push it to 1080p and have good frames... unlike BF4, which I cant run 1080p without it dropping to about 15 fps lol
Loving the game :)
