I've stopped being interested in frontend frameworks after Vue/React but I agree. I find JSX with its mix of JS and HTML rather weird. I prefer Vue's abstractions and the readability of its template syntax. It's also rather easy to add it without a compilation step for some interactivity or app-like behaviour on a web page. More complex applications using a bundler work as well as our company is developing and maintaining a 100k LOC webapp too. In the end I'd prefer it if browser would provide a native API for two-way binding, components or templating and maybe state management as well.
