Without having tried the PS4 version, I can say that CoD: Ghosts was one of the titles that impressed me the most. In fact if you are looking for consistency it might be the best version, in my opinion.During the review, SP was 720p and MP was 1080p. I think some builds were blurred ? That's why some reviewers said they couldn't tell the difference but others could.
The XB1 had (has ?) some sort sharpen filter turned on too.
By consistency I mean perfect framerate. BF4 on the other hand is much more consistent on the PS4 and it is the best version hands down.
On the Xbox One it is still a fun game, especially using Kinect and the controller, but the framerate is unrefined.
When I play on a console I expect a rather solid framerate 90+%, whether it is 30 or 60 fps. I chuckle sometimes at some videos from people with a Titan or a similarly powerful graphics card, they max out everything, the screenshots look insuperable, the framerate is high but then at some points it goes as low as the teens.
If the framerate in a game is too jumpy I then get bored/ frustrated and turn the game off. That's not usually happen but sometimes it does.
