Usage of the Starter Site and the sample catalog

I have a question I would like to get some feedback on.  For those that are building new Commerce Server 2007 sites how many start with the Commerce Server 2007 Starter Site as the base for your new site?

 Also, in your testing how many people use the Adventure Works sample product catalog as you starting point or as a bench mark testing catalog?  How many people would find a more robust and in-depth designed product and inventory catalogs useful?
