I considered Django pretty seriously and worked through most of the excellent Mozilla tutorial.

I prefer Django's having models defined in code and being able to generate views and migrations based off these. The auth situation seems more robust.

Obviously there's direct benefit to me with working with a familiar language.

The decision to give Rails a go instead really game down to me trying to minimise how many pieces I need to tape together. And with Django it seems I'd need to sort out my own frontend story and build my own deployment process. Rails has defaults for both of these now. I'm fully prepared I might decide to rebuild with Django in the future, but right now Rails is working.
