There's two great things about this set (so far that I've seen). First is the letter included by Ridley Scott. "My goal was to give you the film in whatever form you prefer, with the best picture and sound quality possible." That is awesome. Not "Here's my director's cut" or "Here's the theatrical cut" and live with it. We got 5 different cuts and we can pick whichever one we like best.
The second thing is from the features on the Workprint disc. In the behind the scenes feature, the guy that "headed up" the creation of The Final Cut says "We can't call this the Director's cut, since that's already out and I didn't want to call it a Special Edition since the fans would just think that we're trying to get them to buy yet another cut. We had to give it a name that says this is it, there won't be any other versions, this is The Final Cut."
Those are the two most awesome things about this set. We don't have to wonder if we're ever going to get a version with all the scenes from another version and we don't have to wonder if they're ever going to try and "gouge" us again. This is it!
