Since I forgot to mention in the question to vote for your LEAST bias, I made a new poll.

Each round will be based on VALID comments. Every time you comment on here will only count as one vote. Here's a few examples on what I mean for valid comments:

VALID: I chose (insert name here) because (states reasons).
INVALID: (insert name here) | I chose (insert name here).

The voting results of this countdown won't matter to me, so comment! Don't be afraid to speak your mind. If anyone insults someone's comment due to their own opinion, they will be banned.

My Opinion: (I don't count my comment.) I chose Yuri because the appeal that she had before kinda diminished, and ever since I watched Radio Star episode, I found Yuri a little irritable.

Based on vinxinc's old polls.

Mine is Tiffany
I love all the members, so I do not have a specific reason why it is my least favorite, only the other members I like more, but in these last days more'm loving Tiffany (probably up in my list of bias)

My least favourite is Seohyun. It's not that I don't like her but compared to the other members they stand for me more out and sometimes I find her a little bit boring sorry

I agree with Sandra311

My least favorite is Taeyeon because on Radio Star and other programs she seems to not talk as much anymore and she seems bored or tired most of the time.

It's not that I don't like Tiffany, in fact she is beautiful and has an amazing voice. It's just that compared to the other members, they stand out more to me.

Seohyun : She is way too serious and doesn't even appear to be like the maknae of the group.

Yoona, she's overhyped, I don't like her as visual, she can't sing like the others and I don't like too much her personality.

Least fave is Taeyeon. There is something in her that I couldn't fathom.

My least favorite is still Teayeon, I guess. I don't know why though.

By Tiffany That is my least favorite? is rare, I do not like people who talk a lot, and always have to be screaming at each concert, I know she does it for the concert is not boring, but I do not like (I know I'm weird, it goes to rincon by rare Lol)

just something about her that I do not like

Sunny

My least favorite is Sooyoung ... I just like most other members
