The analog controller is great for a lot of different reasons.  The vibration function is a really nice addition to the game.  It may freak out a friend who's not expecting it (which is quite fun to watch) and adds a  nice dimension to games that support it.  The analog controls are great,  especially for driving games.  The more precise control keeps you from  veering from side to side.  The amount of buttons and fingers used may make  people who aren't used to it uncomfortable, but that doesn't seem like it's  going to change anytime soon.
