There's another thread on this same topic about how a mere feature list doesn't capture the experience of using an app. It's faster and prettier, for one thing, it has a friends list that is browsable like the iPhone contacts app -- the Android friends list is just a flat list where you cannot jump from place to place easily, so if you want to scroll to z it's going to take a while. You can't handle requests or send Facebook messages with the Android app as far as I can tell, nor even read your inbox. But a mere list of features doesn't capture the entire difference.
