Linux + VSCodium
I do work and target Windows for a few other projects.
Also, not trying to start a flamewar, but I've spent too much time tinkering on Linux in the past. There is *always* some hardware compatibility issue, or some missing drivers, and especially with GPUs. Linux works best on a server, or on a VM. At least, that is my experience (and I've been on Linux for more than a decade, be it with either Debian, Archlinux, Gentoo, or Ubuntu).
