Well. . . I don't know too much. Let me share what I have been able to learn in comparisons with just a few items.
I personally feel the top most pictured, the most recent of US releases, is likely the best sounding and most complete. This has been true when I have been able to make comparisons, such as between the US and French releases of the RCA Mingus title and two titles by Gato Barbieri. The Mingus US release had more material, more liner notes, and "better" sound than the French release. Contentwise the Barbieri material was the same, but the US version had two titles on one, and was "better" sounding.
"Better" sounding is subjective. . . . Some may prefer the one to the other. I felt that the US versions were perhaps a bit more "full" sounding and less bright.
