If you asked me five years ago I am sure my answer would have been Windows, both for work and home.
But Windows has been getting progressively shittier with each update, and even my employer has been switching over to Macbooks for the majority of the staff. When I have to use Windows, it irritates me.
So, macOS at work (M4 Air) and at home (M1 Pro, although I dual boot Asahi), plus I converted to Bazzite on my home PC a while ago (ex Windows 11). I have some other stuff in my homelab running all sorts of Linux flavours, be it in physical baremetal form or VM's.
I'm at the point now where using a Windows PC feels alien to me.
