I'm working on a big, complex system using an ORM at the moment -
http://gu.com. It's a Java/Hibernate/Spring system rather than
anything Python based, but the principle is the same. We find that the
ORM works great for 99% of our DB interaction, and saves a lot of
tedious fiddling around.

*But*, the 1% is crucial. Using an ORM doesn't mean you don't have to
understand what's going on underneath. When you need to hand craft a
performance critical query, or when you are chasing down a bug, you
need to know SQL, and know it well. C.F. The Law of Leaky Abstractions

It's not either SQL or ORM. It's both. But SQL should come first.
