Which kpop group(s) or member of a group, do you think are underappreciated?

I tend to like underrated members more than the popular ones.

But of course, I also like the popular ones. It just depends on who catches my attention first.

Members -
After School's E-young : E-Young's my bias in A.S and I find her the most underrated. I mean, even Kaeun, the newest added member, is more popular than her! E-Young can play a lot of instruments, one of the better dancers in A.S, and she can sing. I don't get it. She's also beautiful.

Miss A's Fei : Fei is currently gaining attention right now because of the shows she's in but I think she's the least popular among the Miss A members. Suzy's obviously the most popular, Min's known for her being one of the best dancers in kpop, Jia's popular for her always-changing-styles and what about Fei? Not my favorite, Minnie Min is!

SNSD's Sooyoung : I don't know why people think Hyoyeon's the least popular. Soo's clearly the one. Hyo's known in America and western places and for her dancing. Sooyoung's known for being tall. My 2nd favorite after Seohyun.

f(x)'s Luna : My bias. Best in singing, Dancing (f(x) style dances) and looks like a goddess.

Big Bang's Seungri : I'm not familiar with Big Bang but he's the least popular in my opinion.

CNBlue's Jungshin : No one seems to be obsessed with him or something. I like Minhyuk better.

Secret's Hana : Secret's popular but their company doesn't really promote her. Hyosung's my fave.

4Minute's Jihyun : She's popular but her talent isn't. I'm sure that she's pretty good in dancing and she raps. My bias.

MBLAQ's Seungho : He is the main vocalist of the group but you wouldn’t know it because G.O.’s voice dominates all'er songs.

Davichi's Haeri : While everyone only sees Minkyung's hotness and beauty (I know because I'm part of them) I personally think Haeri's the best singer. And although she's not the most beautiful, there's no denying Haeri's the most awesome.
