You can use JSX for Web Components too, see: https://github.com/wisercoder/uibuilder There is no need for a complex framework like React. Web Components + JSX is better than React. Why use a proprietary framework with patent issues when you could be using a standards based solution instead?

React is not complex, it solves complex problems, elegantly. Web components make it worse than it already is. By catering to the dom they fragment HTML even further. Now you rely on attributes for "if", "each", "of", "loop" and so on. It literally enforces frameworks shipping template parsers and script engines that duplicate and fight against Javascript, each with their own syntax. Without frameworks like Polymer you only get encapsulation and that's utterly pointless.

The extensible web is about low-level access. Web components go against everything that stands for. They're again pushing a bad vision that was decided on almost 10 years ago by people sitting in a closed room trying to interfere with how we write apps, resulting in a useless spec that adds complexity and weight. That spec btw took years of pushback against Apple and other vendors that weren't even interested in web apps rivalling their native stores. They have eventually given it green light because the spec is so tame it won't threaten a native app in a hundred years.

React on the other hand isn't much more than a simple idea:

    const Component = ({ text }) => <span>{text}</span>
    const Another = () => <Component text="hi there" />

We can express UI declaratively and functionally. It solves our problems and pretty much has set the web free. Now there are dozens of frameworks that follow these principles, it's made it possible for Javascript to move on to native space, other platforms and devices. We're closer to truly universal apps than ever. Nothing proprietary about it, just technology that has managed to come through by its own merits which has evolved into an actual, living standard.

The W3C has the worst kind of track record, don't expect anyone to fall for all this hand waving for "standards," no one is that naive anymore. If a spec doesn't perform it gets discarded and by this point we already know web component don't.
