I love them both and they're definitely my favourite characters. I think I might like Harley slightly more because she has more personality. The Joker is awesome and I love the way that his character develops but Harley just seems to have more to her, which might be because the Joker isn't really one for showing emotions which Harley isn't afraid to do. She's also pretty interesting because she's quite cunning and is able to fool people with her appearance and 'blonde bimbo' thing. I also love it whenever she gets angry at him. It's always funny to watch!
