The Live In Tokyo is neat for me to see because while I have been a fan of theirs since I&W, I never saw them live till 2003, and it was neat to watch an old performance with them, so to speak, and how they discuss that critical period in their history.
LiveTime has some good parts, and some duller parts.
Scenes is enjoyable as they break down some of the story elements in more depth.
ReUnite is a fun listen but not as "interesting" as the others.
