What do you want the bag to do for you? If you want something a little more elegant that could be used as an evening bag then I would go with the LD. But if you want something that is more "day" bag I would go diorissimo!
Lady Dior of course! Very unique design, iconic, wrapped in history and very well made. Miss Dior would be next but they can't decide on their design. If they keep it boxy with old chain or leather laced chain and NOT the sliding chain and trapezoid shape, perfection!
