With same languages? Whenever I stray away from C#/Java world, I am amazed how bad the IDE experience is for other languages, but that's because most other languages have features which don't play well with IDEs (dynamic typing, templates, macros, anything compile time).
I agree (even though it pains me to). I've thought about it a lot and I think it's because in the Java world, unlike most other worlds, the IDE is basically mandatory. I've worked in a few different java shops and the project was built around the IDE and required it.
In contrast it's really hard to make good C++ code intelligence features. For many many years Microsoft was the only one that had done it (as far as I know).
