Should i keep rerolling to get frigid finesse?

i currently have malice on my amulet. Should I keep reroll to get frigid? Malice seems to be better for boss and less so for mobs. But frigid finesse seems to be better in mob.

Fyi, my blade shift is currently 100% freeze, I also have 100% vulnerable from mired sharpshooter, but my knock down source is only from dash, not sure if death trap is considered one.
