Taking a look at ten different PHP frameworks(Page 4 out of 4)
ez Components isn't so much a framework, but more of a collection of components, and that's probably why it doesn't come with inbuilt support for MVC.
It comes with most of the usual components, like a database component and a caching component, but it's also lacking a few things. For instance, it doesn't have a ActiveRecord component or a authentication component. On the other hand, it does have a few other extra components, like an e-mail component, but there aren't many, and other frameworks (like the Zend Framework) offer more.
CodeIgniter is a relatively new framework, by the makers of ExpressionEngine, and it looks quite promising. Unfortunately, it doesn't handle multiple databases yet, although that is in the works.
It's inspired by Ruby on Rails, and it offers much of the same functionality, like scaffolding. It has excellent documentation, and they've even got video tutorials to get you going.
And the winner is...
I'm going to have to disappoint you here, as there isn't a winner. Each framework offers different functionality, and there is no clear winner. Just like most things, it comes down to preference and personal choice. I highly suggest you look through the documentation of each framework above, and decide yourself which framework you like best.
Personally, I really like the Zend Framework at the moment, but as I've been investigating each framework, I've seen many other interesting features, like Prado's events or Symfony's ORM implementation.
If you absolutely can't decide on what framework to use, you can always do what most people do: write your own. It may take more time, but it's a hell of a lot fun.
