none of them I think. But Soo is still far better than the other two.

^LOL, if they had better technique I think they would sound better

for me yuri.. i like her voice..
but i think soo sings better than her

Soo and Yuri

and soo

easy one

yuri 4 me

Yuri she has a decent voice

I like her low tone voice same with Hyoyeon technique. Sooyoung sounds too chipmunk to me, too jpop.

easy win for sooyoung :)
