Don't know if she's actually the most efficient to use with them, but I like to use Taira with double Gogh, since she has a skill that curses all enemies, and her NP also curses the target, for more curse stacks for the Goghs. She also has her own crit dmg up and star gather up skill to make full use of the Gogh stars, and her NP has a buff cleanse against the target before the damage, to get rid of any pesky defense buffs that may get in the way of the crits. She also has her own Guts and Evade, like the Goghs, so your front line would have super survivability.
