I have all three.. Hawkmoon is good for pve as its basically a sniper with all that range and can cause havoc in both pve and pvp if you know how to get them critical hits. Fatebringer (my fav primary) is just amazing once fully upgraded. It wrecks in every aspect of pve in almost every single situation and isn't that bad in pvp either. The last word? Lol it's so gimmicky. I don't like it one bit. It's just my personal preference though.
