Comparing Youtube with Megavideo

Guys, if you have both accounts from Youtube and Megavideo, what could be your evaluation or feedback in viewing good quality videos? We’ll for me; I have some points in each site that to be discussed in this topic:

Youtube: It has a great Google PR with so many backlinks from other sites either do-follow or no-follow. Video marketing here in Youtube is so useful when its part of SEO strategy, because you advertise your products and services with great innovation.

Megavideo: Not so popular for me anyway, but not high Google PR. What a loser? It’s no match to Youtube because it’s popular and affiliated by Google as well. Survey shows that Yotuube has more and millions of subscribers than Megavideo.
