I use Eclipse, I won't go back to NetBeans. But the reason is the refactoring tools and very nice plugins, not Swing. SWT doesn't come close to being a general GUI API. It was made for Eclipse, and has enough features for many but not all apps.
My app requires inner frame windows, anti-aliasing and compositing, custom window frames - things I can't do with SWT. With Swing this stuff is trivial. Then again, I think Swing has a nice easy API though some people think otherwise.
