Some interesting versions people have listed so far. What I think is most interesting, is the appreciation of the 1997 SE releases - they seem to be more tolerated than the 2004 SE and I can understand why. For example I liked the enhancements in ROTJ 97SE but could not stand the changes in 04SE version - it just went too far.

The Aluminum Falcon, I find what you say about the ROTJ SE interesting, especially about colour timing. I too thought the 2004 version was just horrible - way too saturated and the Vader vs Luke scenes too dark and muted. In the 1997 version I thought it looked improved over the original in places regarding colour timing.
