Need comparison of MVVM / WPF / Silverlight Toolkits

I'm looking for a good article that compares MVVM Light, Caliburn Micro, Prism, and any other Silverlight / WPF / WP7 frameworks out there. I've seen some good articles on them individually, but nothing that really pits them against one another. A开发者_StackOverflow社区ny suggestions?

See this article http://www.japf.fr/2009/10/a-quick-tour-of-existing-mvvm-frameworks/

My recomandation if the app is not too big, better use MVVM Light, and after that deppending of your requirements, Prism(Last Version), nRoute, or Caliburn .
