The other IDE's I've worked with for any significant amount of time are Eclipse, Visual Studio, and various flavors of IntelliJ. Eclipse is the worse of the bunch, but it has a few important features that XCode doesn't. Support for a multi-monitor setup, configuration files that don't cause conflicts every other merge, a complete set of refactoring options. That XCode doesn't have a Search Usages or equivalent for a symbol, forcing you to use text search, is downright weird; they clearly use that functionality internally in the Rename refactoring.

Stability wise, there have been a few versions that crashed a lot, but that has improved lately, so I'm not complaining. And I do love how quickly it opens.

I'm currently using AppCode for developing for iOS, and I find substantially better than XCode. It has a full set of refactoring tools, that I use constantly, better search, it actually creates folders when you create groups (unless you tell it not to, and I think that's the sane default). I'm not sure it's a fair comparison, since it does cost as a much as a Developer License.
