I honestly think they are both beautiful

I think so :)

By far!

Merida is beautiful! Anastasia is certainly not an ugly stepsister though, I like her dimples.

Merida is so purty. Anastasia is too, but not more so in the second movie.

Merida is so beautiful! But Anastasia is pretty too.

Is she ever! <3

I think they're both gorgeous, I think Merida is unspeakably gorgeous, but Anastasia is beautiful. I think Anastasia is actually prettier then half of the princesses to be honest.

I know it makes me weird, but I never found Anastasia and Drizella ugly, even as a child I found them quite pretty. They're beautiful, IMO. But Merida is breath-taking.

...I think Anastasia's quite ugly/homely. Drizella looks better (but she's homely, too)... :| Okay, she looks okay with her hair like that in the second movie, but still not pretty.
Merida is stunning.

^I find Drizella prettier too.

That lucious red hair! She isn't beautiful, but she is pretty. Merida has more of the cool look. Her hair looks cool, but not pretty or gorgeous. Also Merida's face is just really homely.

Merida's very pretty. Anastasia is pretty too, but not as much as Merida. Though I think she looks really good in the sequel.

Merida is very beautiful!

Both aren't very attractive, in my opinion.
