It is a good reading, no doubt. The sound is natural enough - but I could do with more percussion. Rute and triangle in particular are largely absent. Or my hearing is kaput. I really like the no-nonsense way with the Finale. And in the introduction he gets the string tremolos correct - not measured 32nds. (I know, it is a confusing notation, but since virtually everyone except Barenboim and Solti do it unmeasured, I'll stick with it.)
By the way, the Scherchen is with the TRONTO
Symphonic Orchestra, at least on the edition I have.
No one has mentioned versions to avoid - maybe there are too many. But here's my list: Masur, Klemperer, Svetlanov, and Schwartz.
