I seem to be in a very small minority here, but I found the music changes in '97 ROTJ really worked a LOT better. I also prefer the eyebrowless Vader and Hayden as the ghost (or would if he wasn't quite so goofy, but it'd probably be possible to find alternative footage somewhere). It's not like Shaw's been entirely cut from the film, he's still there for his main unmasking scene. My first experience of the OT was in the theatrical release of the SEs and when I watched the OT later I was like "what the heck is this music supposed to be?!", especially in the finalé. It also took me several viewings to realise that the ghost next to Obi and Yoda at the end was supposed to be Anakin — he's too heavily made-up as Vader to be quickly recognisable and from a continuity standpoint he looks nothing like Anakin in the prequels.

A similar thing goes for Ian's Emperor in ESB — keep him if you can.
