I agree with you about community vs single company. We live in a world of a shared knowledge base and a good community will beat out a company. However, I am more interested in getting objective points. For example: 1. Impact on development time? 2. Ease of deployment and scaling? 3. Support from cloud providers like heroku, amazon, etc.? 4. Does integrating java in grails slow the development time? 5. If you have to "break" out of the framework to do something different, is it more difficult to do it in grails or django?
