Perspective from an outsider...

I have always been a game dev but recently I made my 1st web-app, and I looked at React and Angular and in the end I just used basic html, css and javascript + jquery. It just seemed a lot simpler to make the final product rather than use more tools to make it for me at a remove of 1.

Though if I was going to make a giant complex website (like facebook or something) then I would consider React, I defo preferred it to Angular cus it had a more "do what u want" vibe rather than "do things this way".
