After listening to a little bit of each it seems like we are getting three different TYPES of M8s on 1/17. We have the cosmic perspective from Y. N-S, the steadfast no-nonsense Gergiev, and Feltz might sit somewhere in the middle, like the Antoni Wit recording. I think all of these 1/17 releases seem good in their own right.
What an amazing time to be a Mahler fan. We are so spoiled!
