I prefer the new song in the end of ROTJ to "Yub Nub;" it was much more dramatic, but I hate the other celebration scenes mixed in. I mean, how the hell did word travel that fast? And even so, the planets they chose to be celebrating were stupid.

Another change I like is the added stormtroopers in ANH when Han is chasing them down the corridor. He sees just a few in the original and runs, not making sense, and then sees a shitload of them in the special edition and it makes sense why he flees. That was the best addition by far.

And things like the skyline on cloud city, those are nice.
