High PR Blogs V/s MozRank - Which is better?

Hi Guys,

I have a question on high pr blog networks. I recently signed up to a private network to post on their high pr blogs. However, checking on some websites at random, I noticed that while they have high PR (pr 5/pr 4) the moz rank is less than 20.

Does it make sense to post an article with a link back to my money site which has a higher mozrank but just pr2?

Everyone's got their different way to measure domain authority, Google's is PR, SEomoz is Mozrank, and Majestic has citation and trust flow. They're coming at the same thing from different angles - personally I like Mozrank but the others are also valuable

Both of them should consider togeter. What?s more, I perfer MozRank
