I have to admit. I love QtCreator combination with Clang. Nothing even comes close. Visual Studio (despite the factor it is only available for Windows) has serious flow. It parses a big project with small change. That results of huge time waste.

But VSCode and CQuery is the (only?) serious competitor. Particularly if you like more lightweight, terminal stuff. Last time I checked CQuery it was not robust. But I am so glad seeing it is becoming more mature.
