If you set up a node.js project with Webstorm through the Webstorm UI and deploy with a plugin or built in feature you've pretty much get the most fully integrated IDE there is for node projects. It has testing built in, debugging inside the IDE, dynamic updates your browser, supports a ton of JavaScript libraries and npm as well as React and ES6/ES7 syntax. There's nothing else really like it.
IntelliJ based browsers haven't been slow in a long time, but they're even faster now, just be sure you exclude node_modules and library directories by right clicking them and things will move pretty quickly.
