1) I generally prefer Ruby's syntax over Python's (I would miss blocks for sure)
2) Rail's ecosystem seems larger than Django's, but that could just me being more familiar with it
3) There seem to be a lot more Rails jobs than Django ones
Django would make more sense for a business that uses python for other things, though.
Not OP but django is huge and the dependency chain is crazy for me its just way more than i need and doesn't solve a problem that i can already solve with more light weight frameworks.
I have know django developers who were great in django but never got their heads around python beyond the framework.
Maybe things have changed since the last time i poked at it.
