Having rewatched them all the past couple days
I understand that alot of people find the faster editing style ore exciting, but I think it's a disservice to the practical stunt work. The Road Warrior still looks more spectacular to me, because what's happening on the screen looks more real (and is, although Fury Road still uses alot of great old-fashioned practical stunt work). Fury Road also uses some contemporary techniques I've never liked, like the choppy frame rate during some of the action sequences, and over-done color correction. I actually saw the B&W version in the theater, which George Miller prefers. If that version is actually better, it's only because the color correction on the original version was kind of ill-advised.
I still think all four movies are really good. I'd put The Road Warrior first, and the other three in whatever order. I esteem the first two less than I used to because my priorities have shifted, but they're still classics of their genre.
