The whole argument about Angular ten years ago was the learning curve. I’m on a project now using React with Next and find the code so difficult to read or reason about.
Angular has the advantage of being opinionated. There are proscribed ways to do certain things and it’s “batteries included”. React is a much more loose and flexible tool and you’ve got to mix and match other components to have an equivalent framework. This means angular has some advantages when used by less experienced or cohesive teams. It’s easier for a react project to spiral into maintenance hell because you can mix and match tools and paradigms easily. I would expect most angular projects to be easier to understand. React puts all the consistency work on the developer.
