Seconded.

YouTube while it may contain a lot of video of content is really actually pretty poor product IMO. Lots of buffering, lots of ads, the apps have terrible UX as does the website and now that google is becoming less and less trustful (some would say always were but just becoming more evil with more data) I welcome video content hosted elsewhere. I really like Vimeo not just for the performance and video quality but I also find the interface quite good to use, it would probably need some adjustments if it were to take on the amount of content YouTube has.
