Which purple to LB

Hi, I just got another 5* purple aether, and I don’t know which purple to LB. Dr. Moreau or Hannah ?

Hannah is currently in my defensive raid team, but with all these new fiend-destroyers like Gaillard and Esme, I’m not sure she deserves all these hard to get aethers.
Moreau, in another hand, is maybe a good choice as he is very versatile. Not sure though.

My other 5* purples maxed : Alfrike, Victor, Guardian Panther, Jabberwock. Excepted Panther (I used her a lot in mono and against titans) and Alfrike (in very fast wars/tournaments only), they take dust in my roster.

What would be your advice ?

Go with Hannah IMO. Both of those fiend killers are super rare, plus she’s still very useful on offinse.
