same situation here. Had a main account , and made another 1 for giggles , where i got nanaly. I play both now (both are decently high at 160+) , and honestly , i don't mind it.

That being said , nanaly is a powerhouse that will carry you in most maps you will face , so if it were me and i had to chose , it would be her. Despara on the other hand will let you pass the wall of WAR OF MAGIC easily. I say play both and see what you like best
