Although there are some great replies that I'm sure have helped you narrow down your choice a bit, I'd like to throw in my 2 bits.

What i've found is through combining CGI::Application, Template::Toolkit and DBIx::Class i ended up reinventing the wheel and writing login methods, session tracking methods, authorization methods, etc., that had already been done, tested, tried and true by the likes of Jifty, and Catalyst. I worked with both before I decided that Catalyst was my true calling, even after writing Catalyst off as too complicated and "expensive". I chose Catalyst because of configurability, speed, and the ability to get a pretty substantial app up and running in a very very small window of time.

Perhaps you'll have to go through the same rite of passage as I did and realize that the most common web methods such as logging in and CRUD/BREAD have already been written for you via a very well tested MVC.

Hope this helps!
