LaTeX pre-dates modern graphical word processors, if not modern graphical operating systems! How can something so archaic be any good? Well it turns out it was well designed and ahead of its time, which is why it's still popular today. First and foremost the quality of the documents is far superior to word processors. The separation of content and style is in fact quite liberating and makes for simpler writing: you can concentrate on content. And for large documents with lots of cross-references, bibliographies/citations and figures, you'll wonder how you ever put up with word processors!
