It's Honestly personal preference. Me, like others would rather use Thorn because of its DoT, others with The Last Word bc idk the perk or something. And Hawkmoon oh Hawkmoon since I'm an Xbox user I don't have much room to talk about it but 1 shot 1 shawt ermagerd, But my brother does have psn and he has all three exotic hcannons he says he likes thorn because of DoT and its range. He doesn't like TLW much at all mainly because of its lack of range and its upcoming nerf and he loves his Hawkmoon it's just, the Thorn dug its way into his heart
