I'd agree with you if you were saying this about 8 years ago, but IMO the post-jQuery-front-end dust has settled and the "best" (in terms of what most organisations end up choosing) hasn't really changed in a while.

• Typescript unless you've got a really good reason not to.
• React if you have anything remotely complex.
• Webpack (or one of the wrappers) to bundle it up.

Sure, someone may like a React alternative, and that's completely fine. But at the end of the day, most companies are using React because it's basically industry standard at this point, and it's got too much momentum behind it for that to change any time soon.

I'd say the back end is where all the choice is these days
