MAS is powerful, flexible and easy to use
The template system lets you easily skin it and you can use as many or as few of its features as you want to give your site its own unique flavor; the support is outstanding and the built-in 2257 system makes it even more worthwhile.
I think that the bigger your operation and the more sites you have, the more useful it is, but for a solo site operator such as myself, it provides an incredibly powerful platform and wide range of options that can set a site apart from its competitors.
MAS is a definite winner
