Hi,

I use both, Catalyst and Maypole, and for CRUD I think is better to use Maypole if you don't think into doing more than this (CRUD), but if you want to only have a CRUD to have something "on the way" to finally do a Webapps that envolves more things, or don't work standalone, instead merged with your site/app go for Catalyst.

I use both things, I have some webapps like a inventory for our department where I use Maypole, looks great, feels well, and don't spent time to add fancy things or other stuff because I only want a good looking CRUD.
On the other hand, when I need to do a standalone webapps I go for Catalyst, because is more active development there and is cleaner when you want something not-by-default-crud. For websites I use Mason, I'll like it, have many components written, and is very straighforward to create homogenous sites and a nice inheritance model component-based. And you can also combine Cayalyst with Mason.

Regards,
