Well I have to admit that I wasn't even sure who these two girls were until I saw the word TOWIE mentioned and I looked them up, as I can't say I've ever watched an episode.
I voted for Chloe in this one though, as I think she's the one that's naturally nicer looking. The fact I've never seen the show night make me more of a neutral as I don't know what their personalities are like so can judge them on looks alone.
