Help: Is Youku or Tudou Better?

Now that Youtube and Facebook are both banned here on the dàlù 大陆, I'm looking for a new place to put video clips.If anyone has registered for an account at either Yōukù 优酷 or Tǔdòuwǎng 土豆网, could you make a recommendation? Is there some other service I should be considering? I'm most afraid of massive spam on the email address I give them when I register.Thanks for any guidance you can offer.
