Django's ORM is a piece of junk compared to a proper one such as SQLalchemy, hibernate or nhibernate. I wouldn't go drawing conclusions until you've experienced something else.
What in particular is it about my question that caused it to be voted down? I'm actually very interested in hearing the issues that the responder is having with Hibernate. Unfortunately, because they haven't stated what it is that caused them so many problems, it's of very limited value to the discussion being had.
