I'd also say I'm really loving Soojin's style too, she's very elegant and the more (G)I-DLE comebacks there are, the more she seems to captivate me. And Solar too as if you've seen her YT videos she is really good at pole dancing (lol) and is a rather powerful performer overall...
So that would be; Seulgi, SinB, SuA, Soojin and Solar. (all main dancers of their respective groups, except Solar)
I guess those with an 'S' at the beginning of their name are really something special when it comes to dancing!
