In reply to Latinissima.

I feel bad because Ally and Dinah have killer vocals, but seem to lack the "it" factor most when compared to Normani, Camila and Lauren... On paper, Ally is the least popular.

She will still bring it I bet. Only time will tell. I think all of them will at least reach Bebe Rexha/ demi lovato fame. Only 1 or 2 of them will reach super household name, and at this time it looks like most to least successful will go Camila > Normani > Lauren > Dinah/Ally.
