Not overly familler with blm gear. For drg none of the accs are bis and if you are supplementing with other gear sets you really only need 2 pieces of the primary armor slots. If you are not dead set on one or the other I would gear blm with its myth bis first after you zenith the spear. Most endgames only want 1 melee tops, since you have a lock with your other members on the holy trinity already, when you are on drg you will have no lot competition 95% of the time.
