I like Talon Company. If only they actually got a better background, with a leader to whom I can talk to. GNR's propaganda says they kill pretty much everyone they see. True indeed when you play the game. But then I must ask, where do they recruit their mercenaries if they kill everyone?
Plus, it is mentioned in the Rangers' quarters that both Rangers and Talon mercenaries come across one another and that sparks tension, but never ends badly. If only it could happen to the player as well.
Like the slavers, I would have liked to be able to at least be accepted as a "friend" or "contact" for the Talon Company, given the right karma or by helping them. It's a group that would have definitely needed more background and character to be interesting. Because how they're presented in the game, they're just another group of hostile humans like raiders, with a different outfit.
This said, I'll prefer Talon over the Rangers, simply because they're more organized, have more "influence", and well...
Spoiler they seem to be doing at least a bit of goodness by trying to take over the Capitol from the Muties.
Playing as a member of the Talon Company in that level was particularly enjoyable I must say. At the end of the day, we managed to take over the building... with heavy losses of course.
