I'm going to carry on using CGI (when appropriate) for several reasons:

• It works.
• It's actively maintained.
• It's a core module.
• Despite being a huge fan of Template sometimes I just want to print out some HTML for a quick hack. TMTOWTDI and all that.

The documentation style isn't what I prefer, but I have heard as much praise as criticism for it - so I'll put it down to personal taste.

While it's not the fastest thing on the planet that doesn't cause me problems. In my experience you move to a mod_perl environment long before the performance/size issues of the module become an issue.

While I have nothing against the various other modules you mentioned none of them give me enough extra utility to think about moving - or recommending others move.
