Emacs all the way. Love the Emacs.
Been using it for 18 years. It brings to editors what Perl brings to programming lanuages, flexibility, extensibilty, a host of productivity tools, the ability to roll your own tools, the ability to completely change the editor to suit your needs.
Sorry, I get a little carried away about Emacs

Actually I'm getting one of those little 128mg usb key-ring drives to load emacs,ssh and ActiveState Perl on to bring to client sites so I will always have my development environment with me. (Especially since Emacs can transparently edit remote files using ssh or ftp).
