most of the time i use a text editor, vim, but thats because im at work and its quicker for me to work using the linux terminal and just directly edit files(as the machine i use is indeed linux).
Zend is a great IDE although it can be a bit slow at times but it does have nice features, i love the debugging stuff, really useful especially when learning i think because you can slowly step through your code and get an accurate picture of how it all works.

As for Dreamweaver, i used it years ago and it had syntax highlighting (mx i think it was) albeit very primitive.

Tried aptana once, didnt like it as it bugged on my puter, i couldnt select anything from the new project windows etc.
