As someone who has seen via Lucas and the fanedit community so many variations of all the films I find them all interesting and if the original versions were still out there and well cared for I would be happy for Lucas to release a different SE every year for the rest of his life, it's the absence of the original versions that this site and community is all about.
I want the original versions of ROTJ and the PT preserved (and I don't even like them that much) because they are cultural significant films.
ESB is in my view a near perfect piece of cinema but even that isn't as important in terms of cinema history as Star Wars (1977).
