Perhaps intuitive is the wrong word. Once you are familiar with it, it is easy to continue using, and much faster than fumbling around in a GUI trying to find the magic button. For most commands it's also easy to find the necessary subcommand via man or -h or whatever. The other big thing is scriptability, there's a number of things I find myself doing a few times a day, I can throw that in a script (about a minute to do for most of them) and now they take .5 seconds to do, versus waiting for a GUI to load/run -- Plus, now it's my stupid 3 letter acronym I need to remember :P .
