There's an interesting and informed article/review here: Salon Entertainment | A master at dangerous play
Just so everyone's aware (I wasn't until I read the article), the complete sessions set is a misnomer. The 2CD set is the original, with a bonus track. The 4CD set is the original, plus tracks from other albums and some unreleased tracks.
I believe that the original sessions were all August 1969, whereas the unreleased tracks weren't. So it's not really a case of just adding what didn't make the original cut.
It is suggested that the original set is more for the purist, whereas the 'complete sessions' is more for the collector. By purist, I mean that the selected tracks offer what the artist wanted to convey and this can be diluted by the addition of the other tracks, e.g. they only modify ideas in the other tracks and the intention was to bring something new with each track.
