LaTeX makes beautiful printed documents, but my experience is that it's more difficult to generate nice HTML. The ideal system would probably do a good job of that as well: how many more people will look at an HTML version rather than a PDF?
HTML is the most popular when people visit my website to view my resume and PDF is most popular when people ask me to email my resume to them.
