The advantage of wsus is it doesn't use bandwidth constantly for windows updates. Once. The update is downloaded to the server it is deployed to the workstations so only 1 copy travels across the internet. So you could essentially be installing the update 240 workstations and only have 1 copy of the update downloaded. I have several server environments where the computers except updates once a week on saturday night. It is a matter of personal preference when you want the update to happen. All of this can be controlled through group policy
