As you know, I generally recommend using SqlServer for data storage.
But many people have suggested that using RavenDB rather than SqlServer would dramatically reduce the development effort.
My reply to that was that using RavenDB would also lead to a lot more complexity, reduced support by other teams, harder to find DBAs and increased costs all around.
