I got the GB Fundamentals disc mostly for the self-defense stuff to review for testing. That's NOT in the Roy Dean stuff, but it's not stuff that I really train much. (Obviously, or I wouldn't have needed it.)
The lessons are all clearly demonstrated, but the organization of it is geared more towards the individual classes more than watching straight through.
If you're interested, I broke down all the techniques it covers:

As you can see if you peruse the list, some of the techniques are repeated through the course of the discs. Some of them show up 3 or even 4 times. (Click on the "count tab" to see exact counts.) Though I figure the things they repeat that many times are ones that ought to be focused on.
If I just had to get one, I'd get Roy Dean Blue Belt Reqs, especially for personal training use. If you're needing a curriculum to teach/follow, the fundamentals discs would make more sense, as BB Reqs doesn't really lay out class plans like the GB one.
