At the risk of stating the obvious again (like I do on many occasions ;-) : take the three performers and put them on a timeline.
Koussevitzky comes from a past where there was no amplification, all performances where acoustic, recording technology was brand new so it probably wasn't like: "Ok, I liked the third time best, let's do some punch ins to fix some of the sour notes."
Karr developed his technique still with big concert halls in mind (projection etc. because that was what he was doing most) but did not only have to rely on feedback from the audience but from frequent recordings, too.
Paradzik: from what I'm hearing certainly not played with a concert hall in mind and very closely miked to bring out all the small details.
I am not saying one is better than the other, I certainly enjoy all recordings posted in this thread (the vocal ones, too).
