Angular Vs React which one you use

Technology evaluation is some times challenging when we have best technologies available. Let us see who wins Angular or React.
Features

Framework / Ecosystem

Angular 4

Angular 4 is an MVC Framework itself.

React

React is only a view library one needs to choose the different libraries to make the Best Ecosystem. Refer my post for choosing the better parts to build a React Echosystem

Summary: It takes time to build Ecosystem in React. Once built developers need not worry about the Ecosystem.

Technical Skills

Angular 4

Angular 4 requires Typescript which is similar to C# / Java

Need to know about the angular directives/concepts

React

React requires JSX syntax which is similar to HTML and ES6 Javascript

React requires less time to master once the ecosystem build

Summary: It depends on your current development team skills if they are familiar with Javascript go for React if the team is familiar with C#/Java go for Angular

Tooling

Both Angular 4 and React have great CLIs which work with webpack.

PWA

Angular 4

Ionic 3 is a great framework to develop PWA which comes out of the box UI components.

React

We don't have frameworks readily available.

Summary: Ionic 3 is best for PWA development

Story Book

Angular 4

Currently there is no such kind of  Tool

React

Storybook is a React development environment where we can develop UI components independently from the main application. One can browse a UI component library, view the different states of each component and interactively develop and verify components.

Conclusion

Best way to conclude between Angular 4 and React is to develop an PoCs with the cross cutting key features of the project like Translation, Theming, Accessibility, Form factors. I am slightly biased on the Angular 4 first latter having hands on React it own my heart. But if you have a team already working with AngularJS and has experience with Java/C#/C++ sticking with Angular 4 makes more weightage.
