I love the BoS in this game, definitely a different dynamic.
It's kind of funny in that the East Coast Brotherhood is basically what Veronica wants the West Coast Brotherhood to be, and they're succeeding at it; all she needs to do for proof is contact the Lyons Brotherhood.
The Followers are definitely the "nancy boy goody two shoes", if you will. Aside from them, I'd actually call the Kings one of the better factions morally speaking, surprisingly enough. I love how they turned out, the Kings are awesome.
NCR and the Brotherhood are probably about even in terms of "goodness" in this game, with the NCR being a bit ahead. Both are pretty neutral on the good/bad scale.
