I absolutely love both and would get both in a heartbeat! BUT if I had to choose one, FOR ME I would choose the Paddy because IT IS the iconic Chloe bag, and I love it regardless of whether it is considered "in" or "out." I wear my the padlock with pride. Now, that being said, I adore the betty because it is so lightweight and functional. As long as you get what YOU love- you cannot go wrong!
