I prefer the lighter replacements (notepad2, notepad3, metapad) on Windows, simply because Notepad++ seems to always have something to update when I start it on a server. Otherwise it's fine, but not a CLI editor.
And apparently plain Notepad is getting new features now as well. They finally (gasp!) gave it support for UNIX line endings recently. At this pace it's going to catch up with the others in mere centuries.
