The native editors you mentioned (you can’t really call them IDEs, to be honest) are not nearly as comprehensive as Eclipse or Netbeans. If you work on a large PHP project, such as a Magento Ecommerce website with thousands of classes it’s really useful to have proper code completion. I don’t mean basic PHP functions but class names, methods and properties. Also, a class hierarchy view and project outline are things I use every day and are hard to find in simpler software like Coda.

What’s wrong with running something native, intuitive and relatively lightweight such as Coda or TextMate?

I guess it all depends on your needs, but really, these Java apps give me stomach cramps. They feel like apps that belong in the nineties, and on the Windows platform. I respect your preferences, but “best native web developer tools” ? I beg to differ Sir. I suspect that you may have yet to get used to the quality software that is available on the Mac platform.
