In fact, I strongly dislike the 2004 and 2011 cuts, but from a preservation standpoint they don't bother me at all. They are the digital "George Lucas fan edits".
The 1997 versions worry me much more because that was done on film and from what I've read it sounds like they just rendered the CGI scenes out to 35mm film and then cut up the ON to reflect the change. If that's true, that's an almost unforgivable error.
