React is still the best IMO. It's crazy how much you cover with setState and useEffect alone, I barely use the other hooks. Combined with adjacent tooling and paradigms like JSX, React Native, Next.js, I find the others can't quite keep up with the React ecosystem.

I had to use new Angular on a project recently, it's come a long way and it's actually not too bad especially with GPT-4 explaining the reasoning behind Angular, etc. However, it's no React! It's still just too complex, and I can't be bothered to get into decorators, and other quirks that come along with the Angular world.

If you're liking vanilla JS right now, you might like Node - do some backend stuff. It's just regular JavaScript. I think it's always good to stay brushed up on vanilla JS, I do one-off FE stuff all the time in classic HTML/CSS/JS, but for websites my go-to is definitely still React (Next.js typically). I prefer the declarative style, think it works well for FE state, you end up needing some kind of state management usually.
