Angular is much more mature and stable. React deprecates half of their (major) features and changes the way to do (basic) things with every new version.

I have used both professionally at the FAANG I work at and React is simply not a viable choice for a long-term project.

If you had learned Angular on the version 2 and now picked up a project with the latest version (18), 95% of the features would work exactly as you remembered.

React went from advising to declare components as functions, to declaring them as classes, back to functions (and will probably go back to classes in a few versions given their track record). 90% of the resources you will find online will give you code that is either deprecated or doesn't follow the current recommendation.
