Not either of them
if you want to one shot majoris you need the purple block fist because it has even more strength but this one is still solid, a half charge into a following blow plus a little more is enough to put majoris into execute range with the Knowledge of the Enemy class perk that gives 15% bonus damage vs majoris+
The single most important weapon perk is Tides of Battle because it doubles the range of your shockwave turning it into a mid range weapon.
