oof
go tell that to any voice or dancing coach
Dami is a better rapper than Dahyun and Chaeyoung. These two are good in "cutesy" or "melodic" rap, but Dami just has better flow and delivery. Siyeon's vocal range is absolutely ridiculous, and if you thought Nayeon and Jihyo's high notes in ICSM were amazing, I don't know what you'd say about Siyeon's. And she's, like, ridiculously stable. SuA, Yoohyeon and JiU are also amazingly stable with a wide vocal range. Dancing wise, SuA is ridiculously sharp and precise. Momo's very good too, don't get me wrong, but she doesn't have as much sharpness as Sua.
The only thing I'd put Twice above Dreamcatcher is at having more visual (aka being pretty/cute) appeal - and this is not a "talent".
