I know nothing about Crystal---but with respect to Rails and such, the comparison I usually hear is that Django is the Python web framework most comparable to Rails. If that's right, then the difference is really going to be about batteries-included (and the price of that being a high learning curve) vs minimalism and a learning curve of basically zero.
Fundamentally, if you know Python, you can get a useful Flask app up within 15 minutes of glancing at the documentation for the first time. It won't be able to do a lot, but it'll at least be able to take a request, handle the data sent to it, and return an appropriate response. And if you want to do something else, like say talk to a database, you don't need to learn a special Flask way of doing it (there's nothing like Django's built-in ORM), it's just the database tools you already know.
Most of the Flask add-on libraries out there seem like just thin wrappers over existing libraries. Like Flask-SQLAlchemy is basically just a couple convenience functions.

We're a place where coders share, stay up-to-date and grow their careers.
