This guy is fairly correct. Boone is like a Liberty Prime that fits through doors. :gun:
But companion wise he's pretty boring. I'm not into the whole emo bromance with Boone side plot so I generally drag Veronica around for exploring or Cass (when sarcasm is needed). Only bring in Boone when something absolutely positively needs to be utterly destroyed, overnight.
OMG I love that quote. Especially because I can imagine Boone saying in that curt, clipped way of his, "better dead than red"...
Your comments are pretty spot on too, Boone is great for wilderness exploring because things have a habit of just... falling over, before you even NOTICE them even. On the other hand I find him somewhat boring.
Cass is vicious in close range too, with a good shotgun on her anyway.
Also, I don't like that boone kills things at such range I rarely get a hit in, it makes it hard to get achievements and perks for kills/cripples/ect. if I can't get a shot in edgewise. I think Boone slows down your personal advancement in that way.
