I'm going to make this article because I want to express myself about what I think about each member. Hope you'll enjoy it!

Vocal ranking:

1-Taeyeon
Of course Taeyeon, who else in SNSD can challege her? She hits and mainteins her high notes easilly. She has a open vocal range and she's very versatile.

2-Jessica
She's really good but I haven't seen improvement in a long time. That makes me think that she can't improve more, or that she don't want to. Her high notes are amazing and I love her voice, which never change in performance.

3-Tiffany
She's been shadowed for 5 years and now people complain about her amount of lines. She has an amazing voice and talent. She improve really fast. In 2 years she came from 5th to 3rd in my ranking.

4-Seohyun
She's actually amazing, she can sing while dancing, even high notes. She's the best harmonizing SNSD voices and can change her tone easily for each song. But she'll never beat Tiffany in my opinion.

5-Sunny
I'm not a big fan of her voice, even less when she uses aegyo but I can't deny that she has a solid technique. She can hit easily high notes but she can't keep them any second. She sounds exactly like in the studio, what is a really positive.

6-Sooyoung
Best voice among the dancers. I want to place her higher but at the moment I can't. Her voice is angelical and it's also my favourite one but her lack of breath control keep her in the 6th spot. She can hit some high notes but she can't keep them. She sounds really good in her safe zone.

7-Hyoyeon
Yes, Hyoyeon is in my opinion far better than Yuri. She hasn't got a really open vocal but I love her voice, she's perfect for the bridge parts. Some people seem to dislike her voice and tone but I love it. Her low notes are amazing in my honest opinion.

8-Yuri
I love her voice but her lack of breath and tone mixed with no range makes her one of the weakest vocalist of SM. She used to be the best singer among the dancers but she's no longer. I hope she'll solve it because her voice is very fresh.

9-Yoona
The mayority of people say that she is the worst singer and I agree. But her voice is really especial. It's a mix of Sooyoung's and Hyoyeon's, 2 of my favourites voices, and I love it.

Dance raking:

1-Hyoyeon
She's the first at learning choreography and she's really versatile. She can make powerful movements or show feelings with her dance.

2-Yuri
The gap between Yuri and SooNa before was higher, now isn't even observable. I place her here because when she tries she's the best expressing feelings. She can be sweet or sexy, depending on the dance.

3-Sooyoung 4-Yoona
While Sooyoung express feelings better Yoona barely makes any mistakes. Finally I decided place Sooyoung higher because she's one of the members that learn before the choreography.

5-Seohyun
There's a gap between her and the dancers but she isn't bad. She isn't very emotional, though.

6-Taeyeon
When she suits the concept, she does it perfectly, when not, like Gee, at least she tries.

7-Tiffany
She isn't as bad as she used to be. She has improved a lot and I think that she's getting better and better. One thing that annoys me is when she's in showman mode and she doesn't dance because she's shouting at the public.

8-Sunny
Sunny is really especial case. While I think she dances really well, she's never appealing. She just do it. If she didn't make mistakes, she would be higher.

9-Jessica
Not a big surprise, she's lazy and when she tries she is average.

Rap ranking:

1-Hyoyeon
I love her rap in IGAB and Maxstep. SM should train her. She always makes it perfect. She's even able to rap in chinese, do you know how challenging is for a foreign doing it?. Even thought Sooyoung has a better technique, Hyoyeon's voice suits more raps, and she has talent.

2-Sooyoung
She's the SNSD member with more raps and I know why. The Boys, IGAB, Top, Beep Beep... etc. She's been rapping since she was in Route 0, her technique is the best among SNSD members.

3-Yoona
Her raps should be promoted instead of Yuri's ones. The only thing I dislike about her rap is when she tries to be cute like IGAB, but she has amazing raps like The Boys, Trick and Top Secret.

4-Tiffany
That's an especial case. Tiffany has raps that I love, and has raps that I hate. If I use the raps that I love, she'll beat Yoona. If I use the raps that I hate, she's beated by Taeyeon. Anyway, she's the only that can rap in English properly.

5-Taeyeon
Look at me, I want her to repeat it. She's very well-rounded, SM should see it. I loved her rap and the most important thing, she never dissapoints me.

6-Yuri
Ok, you are going to disagree here and I understand it, but it's my opinion. I can't stand her rap, and I don't enjoy it. At least she's better than the girls behind. The only rap I enjoyed so far was in The Boys.

7-Jessica
I have nothing against her rap, but she only speaks fast.

8-Sunny
She has a problem, her voice is way too high-pitched for rapping. It sounds awful when she aegyo raps, and the problem is that she has done it more than twice.

9-Seohyun
Oh please SM, don't let her rap more, we don't enjoy it and neither she does.
