I'm on Win 10, after many years (15+) on Fedora and other *nix OSes. I tried Win 10 for nostalgia (my early teens on Windows) and forgot to uninstall. To be honest, 99% of everything is a browser now... so makes little difference for me!
I am using Manjaro on my home desktop, Ubuntu 18.04 on my work desktop (which I haven't seen in a while) and elementaryOS on my laptop (which is 11 years old and rarely ever used). I also have Windows 10 as a dual boot option on my home machine for Lightroom+Photoshop and gaming. I was on Windows 7 as my main OS until about half a year ago and I am very happy about the switch to Linux.
Arch Linux at home and MacOS at work. To be honest, I have never been able to be productive on Windows.
Manjaro Linux, using it for 5 years now. Love the stability
debian 10.4 because it's linux but very simple. i grew up on 98se and xp but i think win10 soured NT for me. i used 7 for a while earlier this year for a couple programs but now i'm on debian for good because windows is terribly unproductive for my uses - no good terminal (powershell sux), necessary guis, etc.
Arch Linux at home, Manjaro at work. I'm blessed.
Elementary OS, with i3wm.
Archlinux, Manjaro, ArchlinuxARM
Ubuntu! 20.04 here because I prefer LTS as it lets me upgrade less often. One thing I did when I upgraded from 18.04 was a full wipe and reinstall, then scripted the installation of everything, so now I have a bash script that can take a fresh debian install and make it feel like home. Including SDKs, Wallpaper, Apache etc
Win 10 + WSL2 w/ Ubuntu works nicely
I used to use MacOS at work, but now that I'm stuck at home I've been enjoying my Win10 alienware A LOT
Linux user since 2002. Yay, Linux!
after staying win 7 for years and years i just switched to 10
Linux at work because of its file system, Win10 at home for entertainment purposes and UI efficientcy.
