Two way different scenarios where this would be used, so different I wouldn't even compare them. I'd use this to prototype a basic web interface to interact with something like an IoT device. React would be overkill, and I doubt React would be faster to render than this for that scenario. On a slow connection, the fully rendered interface could well be more bytes than this plus some data. I would say first to render depends entirely on what you're doing. React is used in _way_ more places than a blog or ecommerce site.
