Generally prefer Harmy's. The fact that some SE elements are present doesn't bother me as long as I really don't notice them, and all of the DeEd's have reached this threshold for me. The only thing that really bugs me on occasion is the variability in quality (exceeding the already high variability of the theatrical versions).
I've noticed that the DVD downscales of the DeEd's "blend better" by putting an artificial upper limit on the detail, and that limited quality is still higher than any other non-reconstructed source--so for those who can't stand the variability, the DVD downscales of the DeEd's may work better. That said, I still prefer to watch the 720p versions and suffer with the occasional jarring moment.
Honestly though I think it's not so much the resolution, but the colors that push Harmy's work over the top for me, especially for Star Wars.
Back when the DeEd's were at version 1.x, I preferred dark_jedi's work. Still do in many ways for Jedi. Those eyebrows, man...
Plus, I never really adjusted to the whole "Episode IV: A NEW HOPE" thing, so that limits my video options for Star Wars.
I'm hoping -1's work makes this whole "you must choose: high-def reconstruction or lo-def original" dichotomy moot.
