Been using NMM since I don't know how long ago and MO since it was initially released and have generally flip-flopped between them, depending upon what I needed to do. They are both awesome utilities, but were good at different things, so MO won out for Skyrim, but NMM won out for the rest of the supported games. I am definitely looking forward to seeing what comes out of all of this, but have no doubts that the new NMM is going to be one sweet utility when all is said and done.
