Let's discuss php frameworks

I am a php programmer, I work with CodeIgniter. I like to constantly learn something new. Recently, pulled the knowledge of the Zend Framework, tried Kohana, Yii framework. I want to try ORM Doctrine, Propel.

I would like to see comments on these developments in the comments. Who worked as much as they encountered problems, etc.
There are major drawbacks of these developments, as well as advantages.

I myself want to go to one of the 3 frameworks mentioned, but I can’t choose. I like everyone in their own way :)
