The biggest downside of the Mac's global menu bar, to me personally, is that sometimes I lost track of what the active application is at the moment, and e.g. look for menu options for Chrome, can't find them, look to the left, and discover that the menu bar is for Terminal. It doesn't happen often, but often enough, and very annoying when it does. With a menu bar in each window, there's very little chance of this kind of confusion.
