The new version of CFEclipse has just been released. I use this program every day now. The only time I revert back to dreamweaver for ColdFusion coding now is for doing visual interface work.
I think the real strength of the CFEclipse IDE has to be that it's built on Eclipse. The number and variety of plugins for the environment allow you to build your own best of breed development environment.
For me, of course, plugin #1 is CFEclipse. But there are several others I regularly use that allow me to work in this editor and rarely need to leave.
The plugin for vss is top notch and works better and more reliably than anything I've ever seen in an IDE including Visual Studio. Sorry Adobe, but it's even better than the vss integration in either CFStudio or DW.
Back to the new version of CFEclipse. One of the more interesting features that made it into this version has to be integrated support for unit testing with both CFUnit and CFCUnit. I've only used the CFUnit side of things because of the ANT integration thats available, but it totally rocks! If you haven't looked into unit testing your OOCF, this should help encourage you to do so, especially if you work on projects that have lots of far reaching cfcs developed by different people.
If you've been putting off looking at CFEclipse, now is a good time to reconsider getting over that initial learning hump. Once I got comfortable with some of the differences in terminology (workbench, perspectives, etc.) I've never really looked back.
