UC2 is still the more visually pleasing game
I agree somwhow. I find GOWIII to be technically more impressive -for the same reasons you mentionned-, but the warmth of U2 colours, the maniac attention put into almost everything in the game still baffles me. It's a question of style and thus, a highly debatable one.
I also find the violence quite extreme. But as an easy to disturb guy, I had preferred keeping the obseravtion to myself !
