What is your favorite solution for managing database migrations in django?

Question

I quite like Rails' database migration management system. It is not 100% perfect, but it does the trick. Django does not ship with such a database migration system (yet?) but there are a number of open source projects to do just that, such as django-evolution and south for example.

So I am wondering, what database migration management solution for django do you prefer? (one option per answer please)

Answer 1

I've been using South, but Migratory looks promising as well.
