The advantage of Firefox's NoScript plugin is that it can be selective. Say you randomly visit a site and want to temporarily allow the javascript it uses to do its thing, but you don't want to allow any other javascript on the page such as facebook's and google's. The built-in chrome javascript blocker doesn't let you pick and choose temporary permissions at that moment.
