totally depends on the size of your web app. if its simple and small and you only need those two, use the laravel's built-in ACL, gates and policies (episodes 13-16) https://laracasts.com/series/whats-new-in-laravel-5-1
but if not you can use one of these two packages. both are great and well maintained.
