Which fan edits do you like the best im fond of ADMs Prequel Trilogy and EditDroids Original Trilogy. I can’t stand the production value of the official dvds but Revenge Of The Sith is my favorite official Star Wars dvd.
I once thought that fan edits where the beginning of something really new and cool, but since then I have failed to see any one that really "worked". Many are too ambishous and in the end turn out to be crap (lot of the Lord of the Rings edits sounded cool, but seems nobody has had the talent to pull any of them off), others suffer from the fact that the movie is incredible terrible and the faneditor for some reason think the movie deserves to be improved and that they will be able to improve it, and others take a halfway decent to good movie that the editor thinks sucks and that they will be able to improve it and in the end butcher it (Pan's Labrynth Edits come to mind here).
Fan edits that work in my opinion are extended editions (which ADM is fantastic at), and preservations. I really liked ADM Blade Runner Hybrid edits, the quality was a bit uneven (something that I am sure is fixed now) but it really did take the best of both versions of the movie IMHO. The prequel movies have always made good fan edits, just because of the fact that the movies totally sucked, but had some bits that were watchable, so obviously removing the bad bits, if done well enough, would make for something interesting. But to me, even the much acclaimed Phantom Edit or Magnolia Fan edits, which I was impressed with at first glance, have never been worth coming back for a second viewing. I think Mag's first two edits are really hurt by the fact that he never completed the trilogy with a ROTS edit (unless I am mistaken).
All that negativity said, I think Adywan's Star Wars Revisited is one true exception to my negative opinion of full out fan edits. I do not think Adywan really improved on the film any, but what he did do is create an amazing alternative version of the film and show what someone with some true dedication is able to accomplish.
Another edit/preservation/hybrid/extended cut/whatever you'd categorize it as that I have found to be above avergage, and has actually become my definitive version of that particular film, is Ridgeshark's "Army of Darkness Primitive Screwhead Edition".
