We play all three versions in my house (me on my PC, my g/f on her ps3 and my roommate on his 360). Besides small gripes on the game itself, I have never once heard either of them complain about their console versions. From what I have seen of them playing the game, I havent noticed any real difference in the two console versions.
What I can say tho, is my PC runs much better than either of the console versions but not enough to not buy the game on a console (if you do not have a high end PC).
Hope this helps.
