Zend IDE VS Textmate

So I made the jump and bought a MacBook Pro about a year and a half ago, and have been using Zend IDE to develop with (which is what I used on the PC). I’ve bought both Coda and Textmate and can see the benefits of both, but I am having a real rough time giving up all the PHP pluses of using Zend IDE. The others are better for working with multiple languages though…arg.

Does anyone actually bounce back and forth between editors, or know some super ninja reason to go full time Textmate / Coda?

I ask this because Zend can be pretty hefty on resources when I work from home over the VPN. It starts pausing a little to long between opening and closing files and even just displaying directories in its file browser can take a little to long.
