Better unit against Terminators?

I'm trying to decide what unit to field against heavy/elite infantry such as Terminators. I'm running a Kauyon list and I'm leaning towards either:

Breachers with CFB (Devilfish is optional too)

Or

Fireknife suits with Enforcer (either plasma or missile pods)

I'm guessing the Breachers have more volume of fire while the Fireknives are marginally less squishy with the Enforcer? I have Stealth suits/pathfinders to guide either option.

Thanks in advance.
