My favourite documentary is OCP's Deleted Magic. Bar none, one of the most fascinating behind-the-scenes documents I've ever witnessed. Jambe's sort-of unofficial follow ups are pretty good too, and I still haven't seen his SW one, but for me Deleted Magic really made me see my favourite film in a new way, and had a lot of footage I had never seen before.

From Star Wars to Jedi is easily the best of the official OT docs. I'll admit I really like Empire of Dreams, but mainly for the never-before-seen clips. The doc itself is quite fluffy since it has to cover 3 films in like 2 hours and shys away from anything non-promotional, but some of the footage is extremely interesting. I haven't seen Classic Creatures in quite some time, but I remember it being quite interesting (and amusing!) but unfortunately ROTJ doesn't interest me so much. I wish there was a good ESB doc--the lost Michael Parbot doc seems so amazing because the clips from it outshine anything ever officially released at any time for any SW film. Its like the equivalent of TPM's "The Beginning", except for a film worth (re)watching.
