Promises are just as bad as callbacks in most of the code organization issues and I agree with you that they don't actually solve "callback hell". However, one thing that promises (and other library-based solutions) do better than hand-written callbacks is exception handling. By default, promises will capture and propagate and exceptions thrown inside them, which is something that is very easy to forget to do with hand-written callbacks.
