Roundup of Facebook Share & Facebook Like. Which one is better for SEO?

[walidalsaqqaf]

There doesn't seem to be clear cut advice / data on whether Facebook Share or Facebook Like is more valuable from an SEO standpoint.

So I'm asking you SEOmoz fans have you come across conclusive evidence or have your own sites / testes proven that one is stronger than the other.

SEOmoz showed a higher correlation between shares then likes in the last report they did on this, though it was only slightly higher.

I have not seen anything directly, but I assume it's more difficult to get something shared and as such Google would probably value shares more then likes.
