Of the Classic trilogy, I mostly stick to my ancient TR47 laserdisc rips for pure accuracy, or The Classic Editions that came out years ago, with the general exception of Star Wars since he accidentally left a huge CGI shot in the version I have. Though I've been wanting to replace them due to the awful colors and so on. For Empire, there's the recent Adywan Theatrical Edition that's I've been watching.
I'm pretty behind on the latest fan concoctions. I have Darth Editous' original edit, and it's not bad if I'm willing to watch a fan take on the SE. He fixes some things I don't mind fixing, unlike the majority of Georges stuff. Haven't seen the revisited stuff, as I'm not too interested in Super Special Editions, though the unofficial fan nature makes them still better in my book.
I've not heard of Harmy's. Perhaps I'll look into it. Are these the ones purists like me are looking for?
