I’m in an extremely similar situation. I’m a professional software developer, but the software I develop is cross platform, but in practice most of our users are on Linux (Ubuntu LTS more specifically), and a smaller contingent of Windows users. Honestly not sure if anyone uses macOS besides the developers, but we ship best-effort builds anyways. Our developers run a mix of macOS, Linux, and Windows. I’ve used all three, and ultimately while macOS isn’t perfect, I’ve decided it’s what I can be most productive with, for the reasons you mentioned. It’s close enough to Linux being Unix-like, homebrew is sorta like having all the up to date packages like arch, except with the comfort that an update will never completely break my system, and the macOS creature comforts are extremely nice to have when I’m doing more office tasks rather than writing or reviewing code. Hardware is head and shoulders above everything else, I can go a full day without a charger. Great community too.
