I find there's two things which Object-Relational Mappers like Django's provides. One infrequently useful one is relatively constructing queries from user input.
The other is versioning of your database schema, allowing you to easily upgrade and downgrade your databases. Not all ORMs provide this, but handcoding that logic I miss it.
Also I hear many developers don't like SQL's syntax, but I think that's a mix of it being overpowered for them and them haven't really had tried it.
