I've coded in CakePHP, Rails and ASP.Net MVC3, and out of all three MVC3 was the cleanest one for me just because any Model you created was just a simple POCO class. It didn't map anywhere and prevented you from shooting yourself in the proverbial foot. Problems inherent in Rails and CakePHP if you aren't careful.

I even asked a question on SO about this issue, ZERO responses if you can believe that. I guess the silence is answer enough. ;)
