Legion is right out, as I don't endorse the 'burn everything and enslave what doesn't burn' approach.
Yes Man is questionably out, for reasons below.
House and NCR are my choices, but both have their own problems. While I generally support NCR, they want House dead, no exceptions. It seems ludicrous to kill one of the greatest minds of the pre-War era, arrogant as he may be.
Meanwhile, House wants me to wipe out the BoS, which I am also hesitant to do. As crazy as /they/ may be, they also have a vast wealth of knowledge, both pre- and post-war, so it seems crazy to destroy all of the information and technology their bunker contains without some kind of reason besides 'they may challenge my amazing robot army'.
Obviously, I can't continue the game on either case without doing these things, I'm just trying to figure out which is the more reasonable action.
