of the two (though i have only seen ANH in the 2004 version) i have to go with the 1997. cause even though Lucas made changes then that were pointless and what not, the 2004 DVD changes take it to a whole new level of ruining a perfectly good movie.

Some where minor changes, but more (if not all of the changes, not even talking about the mistakes) are just a slap in the face to people who just want the OOT. Anakin's ghost, Fett's voice, new Emperor Dialog, new shuttle scene with Vader. Its truly insulting (im perfectly capable of infering that vader traveled via a shuttle, i dont need you to show it with footage from another movie)
