JSX is more akin to a macro than a DSL, which is why I strongly prefer it. Debugging errors in templating languages is invariably more frustrating and time consuming.

More on point, being constrained within the special language is miles away from the constraint of JSX, which is essentially limited to only allowing expressions, because the macro expands to expressions. Everything else is fair game, and that makes it far more expressive.
