Taeyeon is the leader of SNSD, though it is not quite clear to me why this is. She is of average talent, average looks, and her personality leaves a lot to be desired. One suspects she may be pure, but only because it is hard to imagine anyone wishing to sully her.
Ranking: Mediocre
Sooyoung is blessed as both one of the more talented members of SNSD, and also one of the most naturally beautiful. As the tallest member, and with the best looking legs, she is one of the more sexually appealing members.
Ranking: Sexy
Sunny is far and away the most interesting personality of SNSD. She has a natural cheekiness which ties in perfectly with her smile. While lacking some of the singing prowess of other members, she makes up for it as providing a great positive energy.
Ranking: qt3.14
Yoona is perhaps the closest one can come to perfection in SNSD, and indeed the whole of kpop. She is at once one of the best singers, best dancers, most beautiful and one of the most pure. She is a virgin and perfect wife material. She will make a single man out there very lucky. He will not deserve her, as no one deserves her.
Ranking: Perfection
Hyoyeon is the ugly female one could possibly imagine. I do not see why she is in this group. She can dance, but cannot sing, nor appeal to anyone but other ugly people who identify with her. One suspects she is very nasty in bed, and she is definitely not pure.
Ranking: Ugly, Talentless slut
Yuri is a very beautiful female and very talented. She is a lesbian which allows her to appeal to a different sector of the market, but her beauty is no less evident because of this.
Ranking: Beauty and Talent
Jessica and Tiffany are American sluts and I have nothing more to say about them.
Ranking: American
Seohyun is the most naturally beautiful member of SNSD. She is incredibly pure, and is still a virgin. She has not had any PS, yet still ranks in the top 3 best looking members of SNSD, along with Yoona and Yuri.
Ranking: Pure beauty.
