To explain the difference between DOO and sites@umw, sites@umw is like a beginner tutorial for DOO. It is more simple than DOO like for example DOO has more customizable themes, plugins, and widgets than sites@umw. The biggest difference I would emphasize is the fact that you can take DOO with you after you leave UMW.
( I also played around with admin settings and learned how to change my admin color scheme! )
