Well I will say it is Rewarding and Quick. After going through the walk-through, and getting my head around MVC (in a day or two) it made so much more sense than any other framework I've looked at. I've been nothing but impressed. The defaults of DBIx::Class and Template Toolkit are IMO great choices and made my development easy and quick.

After dealing with the warts in Interchange (not that it's bad, it just can be kinda kludgy), Catalyst was exactly what I was looking for.
