That Savoy/Dial Complete box has the motherlode of stuff on it, but my issue with it is that it was programmed for afficionados/academics rather than consumers, hence the addition of multiple takes of certain pieces rather than just the definitive master. Personally, I can think of very few instances where I wanna hear three versions of the same tune back to back; Miles Davis reputedly hated the CD-era commonplace of padding out discs with "bonus tracks" of workshop stuff from the vaults. "If I wanted people hear all that sh–t," he's said to have remarked, "I would have put it on there in the first place."
Savoy seems to have come to their senses since they issued that bodacious eight-disc Savoy/Dial studio thing, though. You can now get the 3-disc The Savoy & Dial Master Takes, as well as an even more recent 2-disc The Genius of Charlie Parker. And yeah, the live Savoys are pretty awesome, too.
