I don't agree with the prequel music during the duel or the rearranging of the dialog in Obi-Wan's house either, but that's what the Purist Edition is for. :)
I'm still holding out hope that a DVD-9 of the PE may see the light of day.
Other than that, ANH:R is worth the watch and an absolute joy to watch, no matter what version. It's just so nice to see things fixed!
