I think Angular is more accessible than React. I don't think React will be adopted as much by non-engineers. React is usually used alongside significant tooling like babel and webpack/browserify and some flux library. It's probably more complex. You can't just drop some js script file in your HTML document and go with that.
I say that as someone who thinks React is the future of JavaScript development and there's no chance I will ever go back to separate templates so Angular of whatever version is just automatically disqualified. It would be like going back in time and I do not want to do this.
