I've been playing Skyrim on 360. Partly because I'm somehow managed to inextricably become invested in achievement points, and partly because my PC is a bit rubbish. So far I'm happy with my format choice, but those playing on PS3 are apparently having some major frame-rate issues — particularly if their game save goes over 5.5MB.
A patch was released (2.01) that was apparently designed to deal with the issue but, according to Eurogamer's Digital Foundy, the patch only helps moderately. The issue still exists in a very big way, with frame rates dropping intermittently for those with a massive time investment in the game.
Which is a shame, considering that's almost the major selling point of the game - a consistent universe you can get lost in for hours at a time.
Those interested in the issue should definitely head over to Eurogamer for a more detailed breakdown of the issue.
