There's several frameworks that use JSX but don't act like React. I definitely have found myself in the "I love JSX but don't always love React" camp. I used Cycle.JS for a while, but came back to React for the ecosystem.

For what it is worth, I'm rather proud of my smaller reactive (RxJS-based) JSX alternative (Butterfloat), which is not a Virtual DOM like React or Cycle.JS (it is more "What if Knockout but TSX?"), and I am working on its second version now (among other things expanding its SSR/SSG powers, which already have a very different, I'd argue simpler, take on SSR/SSG than the Next.js/Nuxt.js/React Server Components world).
