Not a popular opinion, but to me Camila is the smartest. And she is not only love singing, but she is very passionate about it that she understand/learn what it takes to be better. I underline her wording when disagreed with interviewer comparing them to emblem3:"we haven't completely found our sound, that's why..." She understand. She may act dorky, but her brain is also bright&sharp. I am not surprise if she gonna last long in the industry coz she has the capacity&ability to continue re-invent herself.
