Kanban lets you prioritize exactly the same way, except it doesn't have to fit into a sprint schedule. You also have to make good stories, which are independent, have a meaningful thing that gets delivered and are of a reasonable size. Then important bugs can get moved to the top of the to-do column, and get done quickly as possible without interrupting any in-progress work.
