This post it's not a true "versus" post, one against others. But just a simple post about my love to these two guys:
Notepad++
"Notepad++ is a free (as in "free speech" and also as in "free beer") source code editor and Notepad replacement that supports several languages. Running in the MS Windows environment, its use is governed by GPL License." (http://notepad-plus-plus.org/)
Bluefish
"Bluefish is a powerful editor targeted towards programmers and webdevelopers, with many options to write websites, scripts and programming code. Bluefish supports many programming and markup languages. See features for an extensive overview, take a look at the screenshots, or download it right away. Bluefish is an open source development project, released under the GNU GPL licence." (http://bluefish.openoffice.nl/)
