The biggest advantage to using Vimeo is that it allows you to lock videos to limited specific domains and/or to offer them for sale. I have recommended Vimeo to people for each of these properties individually and used both options myself — we've also done awesome things like embed a Vimeo live stream into our community platform and then have the recording auto-embedded after the event. It all works pretty smoothly once you figure out the initial tech setup. 

Of course it does require a bit of technically know how to get things set up and running correctly - as the "techy" on my team it did take a bit of training to get the rest of the team up and running with how it all works.
