Around 2005 or so, I remember a programmer on another team at a bank telling me that IntelliJ was so much better than Eclipse. I've also written a lot of Ruby over the years, and at some point I was using TextMate because it was a supercharged text editor (not an IDE) that helped with some Ruby things, but eventually I switched to Rubymine which is made by JetBrains. It's not perfect, and I don't use a lot of the IDE, but considering Ruby is a dynamic language, Rubymine does a great job of helping me jump around large numbers of project files quickly to method definitions, etc. Occasionally I use it to go digging into the source of Ruby gems. Refactoring across the project works pretty well too which is harder to get right in a dynamic language. It saves me a lot of time.
