Overall, IntelliJ IDEA is a great tool. I use it mainly for Scala development but it handles C# code well also. The syntax highlighting is great! The integrated tools that I can open in various windows are very helpful. I also like the AI assistant that can help with code development and debugging.
Pros:
I love all the plugins available to the IDE and how well they enhance the interface. IntelliJ IDEA also performs very well as I very rarely have any times where I need to wait long for it to keep up with code changes.
Cons:
The only thing that really has bugged me with IntelliJ IDEA is how it does not seem to handle system shutdown well. Even with all files saved, I must close the application in order to shutdown or restart my computer.
