No, I don't. I and most people still don't understand what Pylon/Pyramid is and their page that tries to explain it does nothing but make the problem worse.
They belong to the same family of interchangeable parts, seemingly used by people who haven't used a web framework that doesn't begin with the letters Dj.
Ok, fair enough, do you have any argument on what "flask does better" than pyramid? Because as far as i can tell, pyramid does more and better out-of-the-box - like extensible permission system.
I would really love to know what IS better in flask, especially since Pyramid oficially supports Py3 and PyPy, and that also seems to be a big thing to me.
