I've recently switched to Kubuntu from Linux and from Komodo to Eclipse.
So I can compare them objectively.
EPIC is great in most of all its features, but its "Perl expression" view seems to be very ancient.. All debuggers are now implements "watchlists".
"Perl expressions" also seems output the result to STDERR, I'm currently debugging Catalyst project, which seems intercepting STDERR, so I'm feeling myself not comfortable with debugging.
In other aspects EPIC is great. Please consider to include debugger improvements to roadmap of the project
