When writing React code I'm always accidentally fighting to make things more complicated than the system wants, naively opting for the former version, and only after some refactoring settle on the latter, simpler (but more numerous) representation.

When writing Angular code I'm always fighting to make things simpler than the system wants, trying to break my code up into more distinct components, and only after refactoring or hitting my head against the wall settle on the more complicated (but fewer in number) representation.

That is, I think, why the comparison between the two is valuable: not because they are libraries that fill the same niche, but because they encourage distinct development styles.
