What's your favorite video hosting site?

By video hosting site I mean sites like LiveVideo, Youtube, Vimeo, Metacafe, etc. Most people are going to say Youtube, because it is the most popular, but I want to hear peoples opinions. Personally my favorite is Youtube, even though the interface looks terrible. For looks, I’d go with Vimeo, because the interface is amazing. The only reason I don’t use Vimeo as often as I use Youtube, is because a lot of the people I subscribe too and love their videos, don’t go on Vimeo. So yeah, whats your favorite?
