I use Komodo IDE which is the Komodo editor and a pretty good integrated debugger. I'd argue that I'm a pretty good Perl Programmer, but I'm biased. I know that having a good IDE and knowing how to use it can make up for a lot of programmer deficiencies!
One of the most important things about a good IDE is that I can write a few lines of code then very quickly check in the debugger that things are as I expect. That saves a huge amount of time that would otherwise be spent poring over trace output or running the code with pen and paper.
Perl is the programming world's equivalent of English
