I agree with the global menu. At least Ubuntu (maybe more) gives you the option to switch between the two. I may be wrong, but I believe it's document-focused vs application-focused?

I think people who like the global menu tend to be single application users (window maximized). If you like to have a lot of smaller windows open on your desktop, then a global menu gets annoying. I also think today's larger screens (for desktop) is affecting the argument that user's find it easier to get to the menu if it's at the top of the screen.
