If Dinah can get it together and gain appeal (her only weakness) she is the real one that could threaten Camila, Lauren and Normani. She can dance better than the two latinas, and her vocals outpaces all three above when she has good breath control. Their last few performances showed she was the strongest overall.

If Dinah doesn't get it together, I still think Camila/Normani will be the most successful, followed by Lauren.

I think Normani's performance aspect and studio songs will do her best, live vocals will be her downfall, but in the world of Selenas, Rihannas, Taylor Swifts and Katy Perry, she will be fine.
