Personally, I am full supporter of both projects. I can't wait to get DJ's BluRays as those are truly the untouched, original trilogy masters that I grew up with. He went through great lengths of restoring the problematic source materials so that they can look as good as possible. I for one am grateful and empathetic to the hell he must have gone through.
Harmy's work is also stunning (obviously), and we're all blown away with the results of his efforts. However, due to the nature of his work, it allows for a great deal of opinion and subjective criticism. Since there is a great deal of editing, rotoscoping, color correcting, etc... we sometimes think of a what we'd like to see done rather than Harmy's vision. For me it's little things like Vader's white saber saber, for others it's the color scheme...regardless they are Harmy's choices to be made. There are no such debates with DJ's work... they are straight and dead on originals.
For me, I want both in my collection as I truly respect the worth of both DJ and Harmy. Both projects have their share of limitations, and yet they both somehow went above and beyond in working with those set limitations. To compare the two is ridiculous and anyone who tries is immediately revealed to be a fool. I will watch DJ's version (assuming I eventually get the Blu) when I am on my own and feel like watching Star Wars as I remember it. I will watch Harmy's version when I am with a group of friends or if I wanted to show some girl I am dating Star Wars... since they will look more contemporary and polished. There are benefits and drawbacks to both... but both are beyond awesome in what they accomplish.
I consider DJ's project to be a true preservation, and Harmy's to be more in line with corrective surgery. To call Harmy's a fanedit is a bit unfair, it's so much more than that. For Harmy, the patient has been in a horrific, deforming accident and he's doing his best to restore the patient back to its original appearance. He's a surgeon with limited tools, and he may have to guess in a few spots... He's putting the original imperfections of moles and warts back on the face (since he's a perfectionist)...but dammit if that patient doesn't look damn good in the recovery room!
