Cobalt Naginata swings faster at a 28-tick use time versus 35, so it lands on-hit debuffs like ichor, procs set bonuses, and reapplies knockback more often — an edge the flat DPS figure understates.

Both are Melee weapons, so the same armor set and class accessories buff either one — you can swap between them without rebuilding your loadout.
