I actually prefer JetBrains Rider these days. Works great for general C# development, cross-platform, and doesn't thrash my disk like crazy.

Granted, I just spent about two years doing Java dev in IntelliJ and recently moved back over to working with C#. I'd gotten pretty used to working with IntelliJ so that probably colors my viewpoint a little, but the JetBrains IDEs do have some features I really like - the class structure pane, for example, is really useful.
