I'm a python guy, so I haven't tried rails myself (I did read the tutorial though). I tried Django and didn't like it somewhat. One thing I don't like about it is that you have to write the same things twice, for ex. specify url resolver and reference it in config. Django is not bad but not spectacular either. http://www.turbogears.org/ on the other hand is! I had no CherryPy or SQLObject experience before, but I learnt the framework and implemented my first web-app with it in one day time! That includes the model, some views and an xml-rpc control interface. That's outstanding productivity if you ask me.
You should give TurboGears a try. -- http://mail.python.org/mailman/listinfo/python-list
