I've never used AngularJS, so I would stick my comment to ReactJS. I would like to point that with ReactJS you have a suggested way of implementing the data-part of your application by using Flux-like architecture ( Redux, Fluxible, AltJS, etc. ). This combined with the views itself also brings more complexity to the application. Still I believe that 5-6 years ago ( when Backbone was the way to go, most cases ), the current state of front-end is far more complicated ( in terms of build tools, css / html defined in JS files, hot-reloading, isomorphic code libraries, etc. ). I'm still missing a front-end workflow, supported by a big company, which reduces the complexity and increases stability.
