Welcome to the Q&A Forum

If you just want the videos watched - Host the YouTube versions, but bear in mind that you'll be sacrificing rankings to your own site as a consequence.

Additionally consider that View Counts don't actually effective YouTube video's ranking position much. More important to improve visibility on YouTube.com is the user engagement (how many peopel watch the video through to the end and then thumb/comment/share it).

With all respect, that article is completely misleading.

While YouTube videos will almost always get indexed on your site, it does not then follow that your site is the one that ranks for them. 99 times out of 100, YouTube will outrank your site with the rich snippet.

Don't think this is a suitable alternative to securely hosting if you want rich snippets - because it isn't. While Yoasts plugin will allow you to get the rich snippet - it won't stop YouTube outranking you for your own video and also only works with a bit of a hack that YT may turn off at any time.

It ultimately depends on what you want to achieve - from both a business and marketing perspective.

If you want video rich snippets and conversions - use a third party solution like Wistia.

If you're trying to improve brand awareness through social engagement, use YouTube.

As it's essentially a show reel and you're trying to get people to come to the website in order to learn about the company - i would suggest using Wistia and focussing on rankings and conversions. The content won't do very well on YouTube, so you have little to gain by putting it there.

For a more in-depth explanation, i have written about the whole subject here www.seomoz.org/blog/hosting-and-embedding-for-video-seo and this advice still stands.
