she's so beyond talented vocally. Whitney level good. But there is so much more to artistry than the voice and look. Its about the personality, its about the other things they bring to the table to keep the viewers interested. Nobody knows who she is, where she's from, why she wants to be an artist, or any struggle or hardship. Just a pretty face with a virtually perfect voice most would say.. but nothing to wow you. Ariana Grande could never compare to her vocally but as far as stage presence + being able to make people look at her when she stops singing.. she's got the race won. Leona is beautiful and talented, she just has her personality locked in a box, or she's that boring. even Adele has personality that shines through.
