The Gomenatics and Cyrunatics obsession is real.
Miley will have her Ciara/Warrior era (the only that kept her relevant was the controversy and her image and I seriously doubt which thing will keep her relevant again but ok

)She'll return to her Can't Be Tamed numbers again.
Demi will be the main interest of HWR so she'll have nice promo and radio plays her music without any controversies needed to back up on so she'll be fine.
Selena might be the greatest seller since she's new at her label and they'll try to make her the teenage Katy Perry.
So I think it'll go like this: Selena >>>> Demi >>>>>>> Miley.
