Technical HW Difference X1/PS4 > X360/PS3
Perceptual Graphics Difference X1/PS4 < X360/PS3
The only exception to this rule, would be Cod Ghost (launch game), Tomb Raider, and MGS Ground Zero, all of which were close to launch games.
Cod & MGS had a 720p - 1080p difference.
TR had a 30 - 50 fps difference. (50 was the average fps for the PS4 version)
