Of all the recent M6ths I've heard, I'd rate the Zinman the best. It has grown on me quite a lot and A/S order or not it is extremely well thought-out, very thoughtful recording with fabulous playing and sonics. I will never be tired of listening to it.
Fischer's version is also pretty good, but I have some reservations about the two middle movts. They sound undercharacterized and somewhat one-dimensional. Some may prefer them done this way because they might actually fit nicely between the two gigantic, ferocious outer movts. But for me, it is Zinman who makes stronger points about the music and its overall structure.
