I've worked on large multi-team Angular/React monorepos. The tooling was lacking for both but Angular feels like it actively gets in your way. React has a lot of churn and keeping your dependencies up to date but React itself is incredibly stable and gets out of your way
My educated guess is that this is clear because Facebook actively uses React, where most Google web properties don't use Angular. There's projects where Angular allows a team to define a SPA UI relatively quickly and pain free. But for large projects, I would continue to choose React. Also, CSS encapsulation with Angular is great until it isn't: it can be overridden only with ng-deep which is deprecated with no alternative
