Which artist sound similar to tripleS members?

I was listening to my playlist and I realised how many idols sound sort of similar to sohyun, e.g classy's hyeju in Psycho and Beautiful, tribe's soeun, hyeju from loossemble and jinsoul from artms. A few others I've noticed is; keena from 5050 sounds a bit like Nien and hana from 5050 sounds a bit like yeonji especially in sos What other idols sound similar to tripleS?
