Interesting. I've never heard the Nott M2, and that's one I'm curious about. I know I 'harp' too much about the organ in M2 and M 8 (no pun intended), but is it sufficient?
As for the Zinman, it is just a tad TOO straight forward for my liking, but the bells at the end are terrific. It's certainly transparent, as you state.
