We use both. I came in with a preference for Django but the applications we build are generally talking to legacy data stores so we more or less lose the Django ORM right off the bat. That cancels out a lot of the advantages Django has, unfortunately.
We use Django for legacy databases, both as a readonly way to access data in a managed data warehouse and to replace an application that had not the nicest schema to begin with. Routers to the rescue.
Of course if the database you're working with is a shambles, then you're going to have a bad time.
