I would say the original ending would be more appropriate in this case since it didn't imply a celebration across the entire galaxy as we know it, unlike the SE ending (especially when Jar Jar shouts "Wesa free!"). As mentioned, the death of Vader, the Emperor and the destruction of the DSII doesn't mean the war was won. The destruction of the DS didn't stop the Empire, it just pissed them off and they came back badder than ever and defeated the Rebellion. I see the original ROTJ ending like the SW ending, the Rebels won the battle, but the war wasn't over as evidenced by ESB. They had a small celebration for their achievements, but then it was back to business.
