I use Rails for my bigger project, but I kinda like Google's webapp (the default on AppEngine). It is enough, and I assume it works the best of any framework on AppEngine.
One of my projects is a location-based role-playing game for mobile phones that we will be launching soon. The entire game engine is hosted on AppEngine and uses the webapp framework.
