At some point it becomes a personal canon question. Some people like the mono mix, some people like multi-channel. All of the original mixes are authentic, so it just boils down to which one you like best, as it would be with video variants (70mm, alternate credits, cloudy composite, and so on), regardless of which ones may have technically made it to the theatre first.

I think I personally didn’t feel any disturbance in the Force until the 93 changes, but they were something I was grudgingly willing to endure at the time. The 97 changes were several bridges too far from the get-go and would never be acceptable, and the later versions were just continuations of the 97 freakshow. Now that we have so many great fan-created options, I wouldn’t settle for the 81, 85, or 93 revisions at all. My tolerance for fiddling has definitely decreased since finding this site.
