Apart from anecdotal experience telling me that fresh JS devs have a much easier time with Vue than React, I love to still have the option to use it through a simple embed without a build system but can switch to a Webpack/any module bundler if the requirements demand it.
The JS ecosystem really has a problem with bloat in my opinion and Vue trumps React in the regard (react eject anyone?).
It's worth noting that React has _always_ been something you could add to an application with just one or two script tags, and the docs were recently updated to emphasize that use case: https://reactjs.org/docs/add-react-to-a-website.html
But writing React without JSX is really not that great in my opinion whereas writing Vue without any preprocessor is totally fine. I know there's the option to use a JSX browser compiler but it's not recommended for production.
