Lore and store and such aside, are there any perks for joining each of the three factions? I'm more interested in what they can do for me. I hear Brotherhood of Steel provides transportation via Vertibird. Also some power armor which I guess you can find all over. What do the other factions give? Don't want to miss out on anything cool for the long haul.

Each faction has a companion you could get a perk from

RR allows you to have special armored clothing.

Siding against BoS allows you to kill Maxson and take him unquie gear and clothing.

Removed the words. Ignore,
