Symphony is a web publishing system made for web developers. It gives you all the power and flexibility you'll need, while keeping out of your way. Symphony's templating engine is pure XSLT goodness. XSLT is a standard recommended by the W3C, so learning Symphony means that you're learning skills that you can also use outside of the system. If you already know the XML and CSS standards, then chances are you should be able to quickly pick up XSLT.
