I am using Eclipse and I find it powerful. The GUI looks nice and feels well thought. The concepts are clear and natural for a programmer with some experience. But what absolutely makes it the best choice for me is the amount of features and the plug-ins. I moved to Eclipse a few years back switching from JBuilder and I have no regrets. The fact that Eclipse is not an IDE but a platform for developing IDEs makes it a winner. With the right plug-ins I can work in the same IDE with most of the popular languages on the market and with most of the frameworks and technologies. Excellent integration with tools like CVS, Subversion, ANT and others make it the perfect tool for the full life cycle of a project.
I am not saying other IDEs are not good or lack features. But some of them are not free and most of them I didn't use. And while probably it would be wise to at least try them, let's face it, the time is scarce nowadays.
