Webpack is fast. Tools like babel which webpack has to call into are slow. Using webpack+babel will be faster than gulp/grunt+babel since webpack can track which file(s) changed & rebuild only those files. Even ignoring that, it still faster because you don't have to kill it & cold restart it when switching branches or adding new files, like with a gulp build which typically globs for files only at startup.
