Herja's fork is the best polearm of the 3 you mentioned. However it's a rare-ish drop from Odin v2 and you would need a good LS to get one. Not to mention having plenty of competition to boot. (Not the easiest polearm to get)
OaT is the second best option, I believe it's a 40% chance to attack twice. It also procs on jumps, making this polearm a beast of a weapon for DRG. Easy to make, fairly cheap as well... Could grind out one of these babies in a week or less. (Best option all around as far as attainability and output.)
Delphinius is cool and attaches a 100% stun to your jumps? I think this is pretty neat and would love to have one for the utility. (Also it has a lightning aura) Could be really cool in PvP too, especially when they seperate the 4 DRG jump's shared timers. As far as damage goes, I don't think this weapon competes with the OaT and Herja's fork. But it's a pulse weapon and doesn't actually exist from voidwatch chests.
