I'll copy and paste the article's list of directors and description:
"* Tony Scott (recently of Unstoppable it's like a missile the size of the Chrysler building!)
* Matt Reeves (Cloverfield, Let Me In)
* Jonathan Liebesman (Texas Chainsaw Massacre: The Beginning, Clash of the Titans 2)
* Duncan Jones (Moon, Source Code)
* Zack Snyder (Watchmen, 300, Sucker Punch)"
I think for most people, it's really coming down to Zack Snyder and Duncan Jones. My vote is Duncan Jones. I just saw Moon and it punched me in the face with emotion. That movie showed Duncan Jones' ability to handle character, and that's something I think Zack Snyder isn't too great with. Go watch Moon if you haven't seen it, it's really good.
