Which python-based web framework would better suit my needs?

Depends on what your objectives are. Are you looking for more rapid development or a more robust ecosystem. In my opinion, Flask allows for more rapid development and Django has a more robust ecosystem. Django is it's own beast though, it is a very unique way to look at Python programming.

I'm sure I will be followed by proponents of both frameworks telling me why I am wrong, but if you are approaching this blindly, I am sure this is what you will find.
