I have actually never had problems with Eclipse. It's still my preferred IDE for JAVA but it doesn't have the same support for Groovy and Grails as IntelliJ. I personally feel the concept of IntelliJ being the superior IDE developed years ago when maybe Eclipse was still heavily being developed. At this point, I feel both are on par for Java development but not so much for other languages.
