I have tried many of the PHP IDEs. I always find myself going back to zend studio 5.5. The eclipse based zend studio is slow and bloated and a downgraded from the standalone version. It's unfortunate they didnt continue the development.
I also played with Aptana on 4 or 5 occasions. I have followed the project for years and just cant make the switch. I always find little annoying bugs or inconsistency. Intellisense is still pretty new for PHP in Aptana, which was another deterrent.
PhpED also fell flat for me. If you are going to use an IDE go with Zend 5.5, otherwise VIM or notepad++ is your best bet.
