I find it interesting that Visual Studio hasn't been mentioned yet even though it is likely one of the most popular in the world. I'm going to say Visual Studio. It is polished, it is well designed, and it makes me highly productive. I've used many other IDEs in my day but am yet to find something as efficient for RAD as C# with Visual Studio. I will say its C++ implementation is only "alright."
