Yes, I am in for ditching Angular for React. I am not comfortable with Angular 2.0. React does the componentization more elegantly.
The answer (as usual) is "it depends".
We've just ditched Angular for React, for whatever it's worth. It works better for our team and we don't have enough Angular in production for the legacy conversion to be a problem.

Not for existing projects - I see no reason to move an existing project to a new framework until the current framework can't do something that needs to get done.
That said, I have strong feelings about AJS 2 being almost a completely different framework and if / when I need to move my existing AJS 1 websites to a new framework, or starting a new project, I'll be choosing something other then AJS 2.
