What about various libraries that don't use a virtual DOM and have vastly better performance than React, for example https://www.solidjs.com or Svelte?
Cannot really say if Svelte is worse than React, as I have much more experience with React itself. My main blocker to adopt it (Svelte) is mostly library support - with React one can use "everything" in all kinds of "hackish" ways and with TypeScript, which wasn't really the case with Svelte last I checked, maybe 2 years ago.
The trick with Svelte is that “two domains” are very, very, close to each other. A JavaScript programmer can learn and understand Svelte after 2 days tutorials.
Library support is something that can be improved only over time.
