I like NM because, in my opinion, they had the best Auto Rifles in D1, as well a Machine Gun that could roll with Life Leech, the only weapon outside of King's Fall to have that perk. Not to mention, their ideology is something sympathise with: care for the people of the City; relaimation of the Golden Age through humanity's own power; solving problems with diplomacy, but taking action if neccessary. It's kind of like how a government should work, at least in theory. I'd trust them to lead the people of Earth far more than a bunch of elmos and a cult.
