I'd say that framework are like, mmm, rails. (RoR was a genius and very candid name.) They allow you move fast and safely as long as you move in the direction the creators if the framework had in mind. Their keyword is cohesion, and their drink is kool-aid.

When you need to move in a slightly or severely different direction, you're better of with a set of libraries. They allow you to build a contraption that matches your unique problem space. They require much more time and thought to achieve the first results. Their keyword is composability, and their drink is a cocktail.

At the start, or if you are a contractor, you want something really fast, so a framework is usually inevitable, unless you're overqualified.

Down the road you keep needing to move across the rails, so you slowly switch to using more libraries.
