Solael's Witchblade vs. Fiend on Hellhound?

Anyone tried them vs. each other to see how they stack up on a pure summoner build?

If you have to pick one, I’d say it’s hard to pick against solael’s for the resist debuff.

I actually sort of ended up answering this question after thinking about it.

Resist debuffs are amazing, yes, but I only have 1 fire/chaos damage pet. And a fire oriented pet build (if such a thing is possible, I don’t know if there are fire based pets outside of Hellhound) would use both anyway. Along with other fire devotion procs.

Meanwhile, the Fiend nuke scales with attack speed unlike Solael DoT (and pets seem to have a lot of attack speed available to them), sooo…
