The IDE Wars: NetBeans or Eclipse for Java Software Development

I’ve been working on several applications for a few years; some are ready or released into the wild. I’ve used NetBeans and Eclipse to develop one application in particular; I’ve written an Earthdawn dice roller application. Earthdawn is like Dungeons & Dragons, but for real nerds.
