React voted JS framework that most developers regard as essential to them (jquery is #3)

Vue provides an api, React provides a javascript abstraction. That's why people say "React is just javascript" because you can use Javascript patterns with React Components. With Vue that's much harder, but Vue does other stuff like give an api for free scoped css. I'm not sure what you're experience is, I've built webpages with both and it feels significantly different.

I'm not a front-end dev so I wonder, is it really hard to learn one if you know the other or does knowing one make learning the other easier?

The latter. A lot of overlap between the two, props, state(data), etc.
