I'm going to give Popeye's a vote because, at least in my experience, the chicken doesn't contain nearly as much grease as KFC does. I'm sure they'll give me the same heart attack eventually, but Popeye's makes me feel better about it. =P
I really don't like KFC, but I have never had Popeyes, much less heard of it. I don't think we have it here. So I will have to vote for KFC, which is unfortunate.
