fran or tamamo cat

It's hard to tell who is better since both are good units and it mostly depends on what you what you want use them for. Tamamo Cat is more durable thanks to her larger hp pool, Morph skill and heal from NP. She also has attack buff helping her in any situation. Fran, on the other hand, is mainly built around dealing very high damage with her NP making her good choice for farming and fighting multiple strong enemies at once.
