Babel is a transpilation library. It takes ES6/7/Next code and compiles it down to a previous standard. It allows you to use ES6, some of ES7 and with plugins, things that are not officially part of the language yet. Babel is usually used to transform ES6+ code so that it can be run in a browser, many of which that are still in wide use only support ES5.
Node is a server-side javascript runtime, while you can use node to run babel'd code (it's just javascript!), you don't need to as node can understand ES6 on its own.
The basic answer to "Which should I use?" is Babel in the browser, Node on the server.
- nodejs is a javascript runtime environment, built upon Chrome's V8 engine. It understand modern javascript natively.
- babel is a polyfill library that allow older browsers (or even older version of nodejs) to run modern javascript syntax (ES6) by "translating" newer syntax into their older equivalent.
- Babel can be used to make es6 code work on browsers that don't support es6 as much as node does,
- Not every project supports the latest version of Node, Babel can compile code such that it works on older Node versions
