I'm still investigating, but I think webapp and tipfy will be a lighter framework than django. Right now, I am using just webapp and the cold start times are already too long. I want to use tipfy for sessions and keep everything else in webapp.
What are you trying to optimize for? Speed of development? Easy of programming? Obscure middleware?
Although I mainly work with Django for larger work related projects (hosted elsewhere) I've tended to use webapp for things on App Engine. App Engine to me is best suited for small webservices that you then link together into a full app, and webapp suits that usecase pretty well. Small hacks as well I always use webapp just for simplicity and speed of development. Examples imified-demo.appspot.com, gitbug.appspot.com and github.com/garethr/appengine-image-host
Downside is tool support, you probably have to hack together little things to make your life easier that already exist in the Django world (eg. a test runner http://github.com/garethr/appengine-testrunner)
Anecdotal evidence from a previous project made me feel like Django was a little slow on App Engine for my liking.
Tipfy sounds a good idea, hopefully a case of App Engine maturing as a platform, although I have no personal experience with it at this stage.
All things considered it depends. A big project with multiple developers should probably opt for Django. It's standard ways of doing things will make life easier for everyone. For one off projects I personally prefer webapp or similar. But set aside some time for building your own tools as well as writing your application.
I would still prefer Django for its structure and a high support available over internet for it and for the following reasons:
Imho..
Django - the only part that's relevant is the templating and maybe the no rel..
Webapp - never tried it after
Tipfy - is what I'm using, seems to be more "pylons" like, has a basic apps/modules structure and lots of "helpers" which quite frankly should be in the google.appengine.api Easy to implement templates and routing is nice. Your pretty much left on your own on how to use tipfy and how to structure the application.
Tipfy
Finally, tipfy has an excellent support community. Rodrigo Moraes is especially helpful and engaging. Questions are answered very quickly, and courteously.
