They are similar to each other (and different from the iPhone) in that their menus aren't always the same, like the iPhone. Apps in both Android & Windows Phone can display information directly through their "icons". Personally, I like Windows Phone better: it is clean, elegant and runs very smoothly. Android can be over-customized, slowing response and becoming cluttered to the eye. iPhones are the simplest: basically, they always look exactly the same.
