> webpack is more simple than grunt and gulp to configure
That's the first time I've heard that one. In my opinion, what makes Webpack great is its raw power and module-based (rather than file-based) focus. Browserify is easy to work with and get started with but less powerful. (Granted, it's quickly catching up.) Webpack is a lot of things, but easy to configure is not one of them.
By the way, Webpack doesn't really replace Grunt or Gulp. It replaces Browserify. That said, if you use Webpack, you can easily get by with npm scripts instead of Grunt/Gulp.
