Rainbow Phasesaber swings faster at a 16-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.
For crowd control, Beam Sword hits with more knockback (6.5 vs 3), keeping enemies at range while you reposition.
Both are Melee weapons, so the same armor set and class accessories buff either one — you can swap between them without rebuilding your loadout.
