Honestly that picture with shadows on desmond's face looks just like the 360 version except someone forgot to click NO-DRAW Dynamic shadows on face close up, on the ps3 version.
Also, if you watch the fps comparison video like someone said, you'll see the framerate is equally horrific on both.
There was no platform preference in this game only the aim for parity, which on two different architecture platforms is impossible, but they got very damn close.
Nobody is a winner, no platform has preference, they both probably suffered for attempts of achieving parity. The fact they have the same AA solution and Texture resolution(Even if ps3 has split ram) proves this.
PS: Playstation version has uncompressed sound, why the fuck do you never mention that digital foundry?
