I think that mixing up AngularJS and Angular (>= 2.x.x) is misleading. They are two different frameworks, so little knowledge can be inferred by combining the data about the two.
As an Angular Dev the most frustrating thing when v. 2 came out was precisely the fact that I had to re-study from scratch all the documentation. As a matter of fact I've used AngularJS since v. 1.1.x (2013) and I then switched to Angular (latest release) as soon as v. 2 came out, and I would definitely answer I'd use it again, but then if you asked me if I would use AngularJS, I would say definitely not.
