Best Free IDE on Mac?

I've tried them all - xcode, netbeans, eclipse, and now jdeveloper. For now jdeveloper is the winner, at least until netbeans is less buggy. Any opinions?
Thanks, Dave

I have no opinion on the free offerings, other than you usually don't get what you don't pay for.

The two I've rated superior are not free: OmniCore CodeGuide and JetBrains IntelliJ. The latter is what I am currently using.

I've heard a few good things about XCode but haven't really given it a go myself.

I've think JDeveloper is a good tool, but I use Eclipse. A friend of mine with who I do some work together at times has it on his Mac. On a "mano a mano" I find very little between his Mac with JDeveloper and my Mac with Eclipse. He works with both, but given all the plugins I've shown him he has slowly moved over to Eclipse.

JDeveloper for me.
I don't want to waste time hunting for pplugins to get such basic functionality as
Visual UI development (JSF/JSP and swing)
XML aware editor
DB integration
And more

I don't bother hunting for plug-ins much either. Personally, I use MyEclipse on my Windows box at work, and this is excellent: Eclipse, plus reams of extras covering J2EE development (JSP editors, XML editors, UML stuff, all sorts), for $30 a year. MyEclipse is also available for the Mac, but I don't have any experience of it on mine -- I tend to just use SubEthaEdit, Eclipse and Xcode at home.

I still think Eclipse is the *BEST* one... I use a G4 PowerBook, with 1 GB RAM, and have noticed that the debugger takes like 5 - 10 seconds to start, whereas on my 3.3 GHz WinXP tower, it takes a half a second...

Do I know you, Mr. Tuttle?

Kindest regards,
