I mean, I would choose the Speedy B 30 but I admit bias as it is one of my favourites. It would be helpful to know what you currently have and what kind of bag you are looking for - are you looking for it to fill a missing hole in your collection, are you looking for casual or something that can also be more formal, something to carry essentials only, or to travel with/carry more than just essentials, do you want something lightweight, how do you prefer to carry bags (shoulder, hand, crossbody?).
