In my opinion:
1. Minji (sounds the most natural, decent flow)
2. Chaeyoung/Dahyun (would be better than Minji but sounded a bit breathy)
3. JYP (decent tone and flow)
4. Vanesya (tone doesn't suit the rap, not really built for a rapper)
i feel like if the chaeyoung/dahyun one was to be updated then it probably would have been first but for rn its
1. Minji
2. Chaeyo/Dahyun
3. JYP
4. Vanesya
