I did one medium sized SPA in react (using alt.js) last year and wasn't really convinced, maybe i did something wrong but i did not feel the amazing productivity boost that so many people mention. Managing a lot of dependencies of the modules i used for various things like forms, file uploads etc has been painful and in general the module quality felt very alpha in many cases so i ended up reinventing what has already done pretty well in angular in terms of functionality. Code organization and best practices also wasn't easy to come by because of the many ways of doing things and in the end some solutions felt more like hacks than a solid implementation. Angular1 is certainly not perfect but i found the whole thing to be much more consistent and Angular2 using Typescript is what i prefer most right now.
