I like it too. People vastly over-estimate the complexity of these tools.
As a freelancer, I start a new project every other week or so. It's really not hard to get up and running with these tools. They're also incrementally adoptable: since most of them are loosely coupled, you can get started with a new one without rewriting your whole stack (for example, I first used React with Gulp+Browserify, not I've switched to Webpack).
