For every small tool you want to use in Gulp you either have to write your own Gulp task in JS, or add a plugin wrapper to the tool as an additional dependency to your project. Doesn't seem ideal. Just by switching to npm scripts you could probably reduce by at least 50% the number of 3rd party dependencies in your build.

Also streaming stuff around inside a Gulp process is good in terms of speed, but imo quite complicated conceptually, and doesn't match the simplicity of piping stdout between one-liner CLI commands.
