The Hawkmoon is my favorite primary overall, but I have to give props to my Multitool as well for being my first exotic. For specials, it would have to be a tie between the Felwinter and the found verdict. As for heavies, it depends on what I'm doing. For crucible, it's either the Thuderlord(if no other exotic is being used) or the Jolders Hammer. As for vanguard, it's my trusty Ole Gjallarhorn: shoot once and everything dies, shoot twice to see hell, anymore than that and it deserves to be living.
