In my work, I have to create and share a lot of videos, and Vimeo is superior to YouTube for my needs. Doesn't auto-play some unrelated content when they are done with my videos, I can easily make basic edits like a custom thumbnail or branding, and it doesn't cover it in their own branding like YouTube. Integrates better into my site as well. So yeah - Vimeo is better than YouTube for B2B needs.
