I don't, but have a feeling I will some time in the not-so-distant future ...
Five years ago, the RCA set left me somewhat cold. Don't know why. Now I'm gaga over it. Last night in the car (by myself, thankfully) I was calling out "Manteca!"
I'm listening to the Savoy set ("Dizzy Gillespie: Odyssey 1945-1952") right this second, having recently listened to the RCA set also. Both are Keepnews productions. The sound on the Savoy is quite inconsistent, but seems to have been subject to less noise reduction than the RCA set.
It's actually a great compliment to the RCA set though, filling in the mid-'40's stuff with Bird and Slim Gaillard, for example, and miscellaneous early-50's Dee Gee material (in great sound, and including early Coltrane on both Alto and Tenor in a 1951 session). One thing I really prefer in the Savoy (and other Savoy boxes I own) over the RCA box are the track listings, which include all the personnel and discographic info with the track listings in one place, so you don't have to keep flipping back and forth to correlate the discography with the track number and title.
Between the Savoy and RCA boxes, I think you pretty much have Diz's studio recordings covered through the early '50's. Then again, you won't see ME posting in the Discography forum any time soon, and I stand to be easily corrected.
You can see the tracks and personnel in the Savoy box here.
