Latent Power or Agitator Charm for Akuma?

Currently working on improving my Akuma build now that I've gotten more into Gog weapons, this is my current build. Trying to think of whether Latent Power 3 or taking Agitator from 1 to 4 would be better.

Alternatively I did just get this charm earlier which seems quite good. I wish it had more slots, but it'd still free up a 3 slot each on the weapon and armor and the 1 slot could allow for Attack Boost 5 or maybe something else crit related.

Or, if there are any other changes beyond just the charms that would suit it better.
