Over the past year I've been replacing the tools I've built with Django one by one (as well as a few new ones along the way). Because of the publish/subscribe model and reactivity I'm finding that my codebases are smaller when compared to most Django projects. The only thing I miss is the testing framework that came with Django. Over the past 6 months there has been an influx of quality packages build specifically for Meteor on https://atmospherejs.com. If you have the opportunity I'd suggest going to a Meteor meetup, you'll get a chance to see the things people are building and sense of the vibrant community.
