I'm a vim guy, but it's wrong to look down on IDEs as pure crutches. They're just tools. In the end, expressive power is conferred more by paradigm and language than editor. In this case, IntelliSense gives you visibility into available methods and their signatures right in the environment. When working in a larger codebase (LLVM in my case), it's very helpful to not have to look up documentation. Then there are tools like ReSharper which you can think of as "higher-order editing" tools that understand the semantics of the code and use it as a basis for manipulation, rather than simply modifying the textual representation of the code. Vim is great at manipulating text, but not as good at understanding the code. IDEs are worse at manipulating, but a bit better at the latter. For most things, I reach for Vim. For bigger code bases, I'm pretty happy in an IDE, as long as it stays out of my way.
