I've never ran into a bug issue (that I noticed) on ps3 or xbox. Only issue I have is I get wore out after 2 hrs because there is so much to do. (It was the same with Morrowind and Oblivion for me)
The only real bug I've had is that a quest NPC wasn't in the town he should have been.
So I loaded up the markers... and he's slightly north west.
Well... the only thing north west is water. Btw, he was inside the city zone and not the world map zone ~.~
so I had to do some tricky jumping and fall through a house rooftop, then make my way outside the walls and walk the world map for 5 minutes.
It looks so different >_>
and then I made it to the ocean and I had to swim for a bit and I see him floating at the top just standing there. I talk to him and then I have to go back into town for something then come all the way back out there glitching again to reach him just to finish it!
