Community here has been pretty negative on this lately. So I'll just add I've been using Angular 2x and also Ionic 2 the last year or so with great success. One real benefit we saw was the ability to take a lot of Backbone code and just quickly port it (models to services, templates just back to html for a component, etc). This is helping us help our enterprise clients in conversions of both older front end code and older Java EE code (for example JSP + Struts => Restful + NG2X).
