I've contributed to ag and followed it quite closely. That being said, I still have ack on all my systems because sometimes, being able to just do:

Turning things around, I often have SQL dumps around, so ack --no-sql is a real lifesaver in my Rails (i.e ruby, coffee, less, shell and whatnot) projects.
