The “modern” JS frameworks like Angular, React, Vue etc are all capable of making very good front-end applications. If WP decided to do with something more esoteric it could be an issue – but I’d say to people worried between these frameworks: any of them is up to the job, what’s more important is just a somewhat arbitrary decision to just chose one.

If you think your framework is objectively the best, you probably need to get our the bubble and try some others. Most of it is down to preference of how you prefer to program. Personally I like React / JSX – but I’d be happy to contribute to Core in Angular if that decision were made.

As it happens I think there is not a lot of value taking too much time to compare all the specifics of the aforementioned frameworks beyond, if it has an ecosystem, energy behind it and been used in production apps I’m happy to learn it and use it.
