For me JSX vs HTML templates depends of your organization and workflow. If you’re a solo dev or in a JS heavy team, I think JSX can make more sense. HTML templates on other hand give a lot of power to non dev. It works well for our agency with our web designers, they can handle all the logic in the HTML, so much that on some projects no additional JS developper is needed.
One difference being that vue templates appear to be hard to make type-safe i.e. hard to benefit from type-checking, whereas jsx is syntactic sugar for JS, and supported by typescript.
