The stability and integration of all the extensions makes the upgrade worth it in its own right. Even though I don't use the wizards so don't really benefit from that side of things, just the speed improvements and reliability of the extensions made the upgrade worth it.
Plus not having to install individual extensions is great, and everything is neatly placed in WebAssist menus in Dreamweaver (apart from eCart which I am sure will follow)
My recommendation would be to upgrade to both DE and DB. At the prices WA charge you will very quickly get your money back.
