My ranking would be, going purely based on speculation about how much money they are earning right now from their solo activities:
1. Jisoo
Dior's main girl. She has appeared in every major magazine (Vogue, Elle, Harper's Bazaar) in Asia at some point in 2022 and her face is currently all over Korea as part of the Dior Addict campaign. Her drama was not well received domestically but considering it did fine on Disney+, the fact that she still has Korean endorsements, and the media turn out when she pulled up at that Dior event in Seoul she is far from blacklisted in SK. Her solo is also guaranteed to sell at least 500-600k
2. Irene
Probably makes next to nothing from solo activities currently, but was a former it girl so that counts for something. Her acting debut and station songs made zero noise. Personally I don't see her making a comeback as an it girl or ever getting a solo but she was huge in her prime
3. Tzuyu
She could have been an it girl but was held back by her company. If she ever leaves JYP, I think she can make it big in Taiwan as an actress/model.
