It may be distributed over a larger number of pieces for both, but - in the end - I don't think you can criticize either for being a slouch.

Especially Sun Ra, who took so much dedication to his music that he and his band often hand assembled records for sale before shows. Why? He was doing it entirely without the influence, or funding, of any group which might interrupt his creative process. Sun Ra poured his heart, and soul into his music 24/7. It was his life, and I doubt there were many moments in the day where he wasn't at least contemplating what he wanted to do with his music.
