Who is prettier? F(x) Krystal or sulli?

I think Krystal is waaayyyy better! She's really pretty and good at singing~

I don't find Sulli as the most prettiest person ever... People say she's the prettiest, but to me, no way...

No, i'm not saying she's ugly. She is good looking but she's not the prettiest person in the world.

Anyway, Krystal is pretty, Sulli is cute.

KRYSTAL!

She's gorgeous. She's edgy but sophisticated when you put her in a lot of eyeliner and her hair like in Nu ABO but she can totally rock the typical Korean, clean, natural look too.

She's very versatile and always looks good. Like when they performed La Cha Ta in the rain she looked beautiful even though she was soaking wet. Or when she was on Dream Team she still looked so pretty.

Sulli has a cute look to her. But if you showed me both of their pictures and I knew nothing about them I'd say Krystal is the more beautiful one.

She's just a very pretty girl. And the fact that she's turning 16 later this month is just, wow.

I've seen both of them in person before, but I have to say that Sulli is pretty and cute at the same time while Krystal is just a plain sort of pretty.

i think it was sulli... as i observed on their old photos.. sulli is still the same but krystal kinda change a bit.. i'm not sure but i find sull as a beautiful young lady..

CLEARLY Sulli. You can't tell me with a straight face that Krystal looks better than Sulli. She's so young, but Sulli has a dazzling sort of beauty. Krystal looks very average. Even though I like Krystal more than her sister and I believe that Krystal looks better than Jessica, in NO WAY does she look better than Sulli. Sulli is young and gorgeous. People are only saying Krystal because they are so caught up in that Jung sister nonsense.

Personally, i think Krystal is prettier,

Krystal is like a natural, charismatic, beautiful pretty.

Sulli is like a cute pretty

Sulli^^♥

hmm , both are okay . n' i think the prettiest in f(x) is victoria !

if i must pick one for them , i think krystal is prettier . she's pretty . n' sulli is cute .

I think Krystal is the best looking. One thing that is nice is that there are very few or no unattractive Korean female singers.

I think both but sulli can be cute and pretty :)
