AFAIK Wistia comes with some great features but I am also concerned on missing out on the Youtube/Vimeo view count (if it means anything).
It depends on what you are attempting to capture. Are you creating buzz for a new brand, product, or service or an existing one. If you have an existing brand use your base via an incentive. If it is new, you can use the same strategy but it must be focused on the intended demographic.
