I have Ubuntu as main OS of my notebook and use Windows inside a Virtualbox VM. 1) Ubuntu 2) Linux as main OS, Windows in a VM 3) QtCreator 4) build within QtCreator (cmake / qmake) 5) both gcc and clang (MinGW and occasionally VS on windows) 6) Inside QtCreator using gdb 7) within QtCreator or with git cli (remotes on gitlab) 8) my personal feeling.... Windows :) Main thing here is that in my personal opinion QtCreator is *much* better than VSCode for C++ development (unfortunately I have to use VSCode for other non C++ projects and I find it quite messy and chaotic).
