I liked the original ending of ROTJ that doesn't show all the planets celebrating. The latter ending is just too contrived. We're led to believe that the entire empire is overthrown in one night, when in reality that wouldn't be the case at all. No war is ever won in a single evening. I also liked the lonliness of the original Endor celebration (without the inserts of other planets); gives the sense that, at the moment, only a handful know about this great victory. And that's more realistic.
