Node has a different use case, Angular is needlessly complicated and Svelte doesn't have a mature enough ecosystem.

React is not all that great. bit it has one giant advantage, which is it's huge ecosystem and userbase. Basically anything you do. there is a library for that optimized for react. Basically all libraries that could be used with react provide a react specific version or utilities.

Also for me, it was just that there is a lot of work for someone who knows react.
