Your list of pros and cons was pretty good. These grounds are still moving and it's difficult to give a simple general answer (it would be easier to give advises knowing the constraints). A major difference between schema based validation techniques (DTD, Relax and W3C XML Schema) and schematron is that schema based approaches are strict (they forbid everything that hasn't been allowed) while schematron is permissive (it allows everything that hasn't been forbidden). The tools and your overall architecture may be to take into account as well. For instance, if it's important that your validation is done directly by a XML editor, it may exclude Schematron and Relax (and even W3C XML Schema depending on the tool and on your schedule). If you can are defining an environment where you can pass your documents into steps that you fully control, the choice is more open which can also bring composite solutions (such as a transformation to prepare the document to fit into a specific validation system).
