The main advantage that a dutch oven has over a crock-pot (or, in British English, that a cast-iron casserole has over a pottery one or a slow-cooker) is that you can put the dutch oven on the hob.

You can also put the cast-iron casserole in a firepit, and cover it with charcoal. Sadly, apartment landlords tend to frown on firepits in the kitchen, so I can't do this regardless.
