Rob Eisenberg and his nimble team beat Angular 2 to the punch all the way back in July when Aurelia final was released. Before considering Angular, considering checking out http://aurelia.io - easier to learn, no third party dependencies and great support. I applaud the Angular team for sticking it out, but I am afraid they released far too late to compete with the likes of React, Vue and so on.
I now have several Aurelia apps in production. I've also created an app in Angular (v1), and another using Ionic (v1) - which was great. But, I can't express how well Rob and his team executed on this project. Documentation could be a little better in a couple areas but this is a place where they've done extremely well also (contradiction I know - but, for example the cheat sheets are amazing and documentation is complete on most things but there are some classes that are still not documented well enough). If you want to develop in Aurelia - just the community on Gitter - they are extremely responsive and very helpful.
The documentation has been improving since January, and I expect there to be plenty more in a short time because for over half a year they were focused more on getting from beta to a full release. But even with the cheat sheets it felt like there was plenty to get work done because the complexity isn't so high with Aurelia - less to get confused about! And I agree about the Gitter channel being very friendly.
You might be underestimating how much inertia the Angular name has in larger enterprise dev shops. They're still creating new projects in Angular 1.x, and will eventually starting using Angular 2 just because it is called Angular.
