For me a large part of a good IDE is the debugger with mouse-over variable contents, breakpoints in the source, and all that sort of stuff. With lack of debugging, initial pain in getting it installed and a UI that I needed to grow into Eclipse/EPIC had nothing to offer me. We spashed out for Komodo Pro and I already had a personal copy at home.
I'm surprised that you don't find Komodo quick for small scripts. I typically have a "noname.pl" edit tab open that I use for checking short scripts - SoPW code for example :). Editing takes the time it takes regardless, then running the script is a single key stroke or mouse click. What could be faster?
You noticed that Komodo is now available for Mac?
