Somewhat reluctantly, VS Code; but I'm checking out CLion as well and not hating it as much as I did last time.

I find CMake intensely offensive, just the whole worldview of every tool demanding you learn some DSL to do basic things when I have a 4K monitor and just want to select a bunch of cpp and h files to build, but I've since been forced to swallow this bitter pill for work reasons, and I guess it's time to give tools based on it another go.
