I'm really annoyed with her right now (actually the last 2 seasons) but she has her amazing moments, and overall she has a good heart and a beautiful personality.
Katherine is beautiful too (after all, she's played by Nina Dobrev) but IMO she puts on too much makeup 90% of the time, which cheapens he look to me.

I think Caroline's personality is my least favorite thing in the show and well Katherine's looks rock ♥

Caroline :)

love her

both

Caroline's personality..I love her and I don't find Katherine pretty at all.

Katherine's looks and personality

Caroline's personality is definitely one of my favorite things <3
Kat is really pretty tho

She's so beautiful.
I really don't like Caroline's personality

I love Katherine <33 and I don't really like Caroline's personality...

Katherine/Elena/Nina is the most beautiful person ever! But I love Caroline's personality! I would love to be friends with her. However, I agree with some other posts that I don't like her at all in season 4 or 5. She is snotty and so selfish. Not talking about sleeping with Klaus and upsetting Tyler. I'm talking about how she has been treating Elena.
