You are right, though that was unimportant to my WP sites. But I should also suggest that you might write also about the big changes in how wordpress.com his making multiple site management so much easier. I fired ManageWP recently because of it. Since WP auto updates, and wordpress.com does so much more, I am saving $500 a month just in not using ManageWP - as McDonald's says "I'm Lovin It"!

The main reason I like AAU better is older plugin, very well maintained and updated. I shy away from fresh release plugins unless I am forced. Plus it simply did what I needed.
