I personally did not like KKG when I went through rush. But if we had to rank their personality, I would have ranked them low. They seemed extremely insincere. I HATE when I use stereotypes but they (the ones I spoke to at 21 and 14 party) seemed like the definition of a "sorority girl." In a bad way, unfortunately.
But, that's not a part of this ranking on the website.
They are beautiful and seem to be well known, so good for them, I suppose!
