We use XSDs to generate JSON Schemas. The schema converter also generates code to convert JSON files to XML, so we can use our existing XML infra while we migrate. As you say both can be used to validate input and to generate typed code. However I find the XSD design tools better, so I expect we'll be doing the XSD first approach even after all our integrations are JSON native unless something radical changes there.
