If I look at their acting skills they both are actually good actors the only thing is that we have a more diversity with Sooyoung, but that doesn't make her a better actress. Yoona has been good girl and mean girl and did them both very well, her problem is the roles she is getting and how often her acting is. I think higher of Sooyoung for the fact that she isn't cookie cutter but I don't Yoona's skill away either.

So until I see Sooyoung with a track record like Yoona, I will have to say professionally Yoona is a better actress.

for me Yoona is the queen of theStarring in SNSD

Yoong

SNSD Best actress (FOR ME)
1. Yoon
2, Soo
3. Yul
4. Jess

1-Yoona 2-Soo

actually, in acting~ the two of them are tied in my list but i think Soo's a little better like 10% ^o^~

Sooyoung is better, come on. All Yoona does is trying to be pretty, and that's it.

^She has done other roles where her goal wasn't to be pretty, you have to give credit where it is due. The only difference between Sooyoung and her is that Sooyoung just goes a little extra, they are both creditable actresses(though i think Sooyoung is slightly better).

Yoona is better

yoona is the best

this is a no brainer LOL

i find it funny how the people who chose Yoona, don't even explain why she's better..they just automaticaly choose her..i bet none of them watches Sooyoung's dramas, including Cyrano

^I explained why I voted for Yoona, despite my personal opinion

LOVE RAIN
YOU ARE MY DESTINY
CINDERELLA MAN and Many More...
