JYP basically never solo promotes twice and YG never promotes females in the first place.
I personally prefer Chaeyoung’s rapping, Singing, and overall voice to Lisa but Lisa’s dancing to Chaeyoung.
Internationally, Lisa would be more successful due to her and Blackpink’s international popularity but in Korea Chaeyoung would succeed Lisa since Knetz don’t really like Lisa cause they’re racist she’s Thai and Twice has a bigger dedicated fandom than Blackpink. Chaeyoung is also probably more popular in Korea than Lisa, for the same reasons I stated before as to why Chaeyoung would be more successful in Korea than Lisa. Idk tho, I’ve never been to Korea nor do I speak Korean
