You even got a tweet from Pete Hines saying that he walked up to Todd playing the game and was incredibly surprised when Todd turned around and had a PS3 controller in his hand instead of an xbox 360 one... This alone tells you the differences between the 2 are minimal at most. Bugs will exist in both releases, probably a bit more in the PS3 version but to be honest who expected any different?
And in the end I will enjoy the game on the one platform which is clearly better than the others, the PC. And my friends who have the Xbox version will enjoy the game, and so will the ones who have the PS3 version. Sure bugs can be annoying but if you don't want to buy the game because you havent had screenshots or footage or previews from your console, then honestly you don't really want to play Elder Scrolls V: Skyrim.
