Arch. I got it working 3 years ago, it's still working, stable. On my main laptop, though, I'm running windows, and planning to install Fedora when I get the chance.

I use NixOS on my pc, laptop, and server, although I dual-boot windows on my pc to play some games.

My phone is android, I have a pinephone but I can't get discord and other things to work well on it so it can't be my daily driver right now. (I know Matrix chat is better than discord, I even host my own instance, but everyone in my school uses discord so there's no way to switch).

My work machine is macOS as the company won't let us use Linux. My home machine is Arch Linux (obligatory "BTW") which I migrated to after Ubuntu dropped Unity and started forcing Snaps on everyone.

However, a nice shameless plug for my Terminal file manager: DF-SHOW which is designed to work on all Unix like systems.

Linux Mint Xfce here - just right for me - not too splashy, not too hard core :-)

Void Linux is home. Plus, as soon as word got out that Windows 11 had those insane system requirements and the TPM stuff I decided I would abandon Winblows for good once 10 reaches end of life.

Linux Mint has always been my recommended for beginners to Linux and if I just want something stable and quick to set up.

Arch (usually EndeavourOS) when I want to do fun stuff.

Due to computer games, my desktop PC runs Windows 11, but my dissatisfaction with Windows is growing. I use MacOS on my MacBook Pro because it works so nicely with my other Apple devices, but I need a change every now and then and try new things, so I installed Linux Mint Cinnamon on a relatively old laptop and it's a great pleasure to work on it. So at the moment I would say that Linux Mint Cinnamon is my favourite operating system.

Gentoo when I want to do Linux at an enthusiast level and out of technical interest, and PopOS when I just want everything to work.

Run Arch on my main PC. Proxmox on my home server with Ubuntu server as VM and random containers.

I'm using macOS also but I'm a arch/Debian guy. i know both of them. I'm not an expert but before macOS i was using Linux. I came to macOS cause of school just wanted something solid. I still help people though if I can with Linux problem when I can

Arch for my main, Debian for my servers and family. I bounced around for a while over the years. At some point in the past I decided I didn't want to use derivatives and these two fit my needs prefectly.

It used to be MacOS, but I jumped ship as soon as iOS stuff started creeping in years ago. Because I had already jumped ship from iPhones for the exact same stuff. Arch is my *nix of choice these days, or Linux Mint if I'm recommending it to someone else who doesn't want to learn Arch.

But with that said, my daily driver is a Windows machine these days. I'm getting lazy as I get older, so (relatively) effortless compatibility is king.

Arch Linux. Once you get past the intimidating reputation it's really nice, and the documentation is best in class.

NixOS for several years now. It's a big up-front cost but you can't go back from atomic upgrades and rollbacks.

My progression was: Mandrake, OpenSUSE, Ubuntu, Gentoo, Arch, NixOS. At work I use Nix flakes on Debian machines, so one month back I figured out I could install NixOS at home to get familiar with Nix. NixOS is really something different and it brings me back to the old times when Linux was new for me. It’s again an adventure!

EndeavourOS. It's Arch but without the faff, it just works and looks gorgeous.

Void Linux and NetBSD.

I was using Pop!_OS for a long time, but finally switched to Fedora and I love it because it feels so up to date.

Fedora.

I've also been getting more familiar with CoreOS / SilverBlue recently.

I use whatever is the best fit for the work I need to do. I mainly use macOS, and try to get away with using VM's with macOS as my host system whenever possible.

I used to be on the Arch bandwagon but after migrating to a MacBook for my daily driver computer it's mostly just Debian-based distros when the need arises, Kali for work and headless Debian for homelab stuff. I rarely boot my Windows gaming PC anymore. I do have some Windows VM's for testing exploits and payloads. And emulated Windows 95-98 machines for that OG Oregon Trail fix.

I'll probably have to go with FreeBSD for their minimal base and incredibly clean and well-documented code and utilities.

I'm currently using Nobara a Fedora fork and upgraded today to version 38 it was a bit of a stretch. I had to delete many things in my /etc/ to get GNOME 44 working. Bluetooth and the panel on the top right is a bit buggy but it works.

On my laptop I use arch with hyprland

I'm a grumpy old man when it comes to OSes. I started on Gentoo, used Arch for a while, a few years of Ubuntu, then a bunch of different Ubuntu-based distros, Fedora and all the Fedora spins, even ran the Hannah Montana OS as a meme for a week.

Eventually, got bored of the latest shiny things and fixing the best thing ever, and am using Kubuntu with Wayland. It just works, got no complaints.

I want to like macOS but Apple, IMO, is doing scummier and scummier things with it. For instance, I haven't signed in to iCloud. Once a day it seems, I'll get a little notice telling me that not all functionality will work until I've signed in. Ok.. So I click the little 'X' on the notification. It opens the settings to the iCloud setup screen. That's not what 'X' is supposed to do!

Kubuntu. I like KDE and been using Ubuntu-like OSs since 2007.

Not Arch!!!

I have tried them all. The one wo never let me down was Debian stable. I use it for 8 years now on desktop, gaming rig and server.
The ones that come close are Alpine Linux and Ubuntu LTS.

I've been on Linux Mint (LM) for like 3+ years now. I was dual booting Windows, but after not booting into Win for over a year, I wiped its hard drive and started using it as backup storage. Before that, I did the rounds (Debian, Fedora, openSUSE, Ubuntu, etc.), but mostly stuck between Kubuntu and LM. LM just seems to work the best for me. Never have any difficulties with anything and love how I can customize Cinnamon. It really just works out well for me.

My first foray was with Ubuntu and Mint, and I found the whole experience far too on-rails for me. A few years later, I made the permanent move from Windows to Arch, largely because of how good their documentation on GPU passthrough via OVMF/VFIO was. It was also an excellent opportunity to be forced to learn how my computer works.

Ironically, I almost never open virtual machines for gaming, I have come across very very little that cannot be handled by wine, ge-wine, or proton.

macOS at work and Debian on my personal computer.

Slackware. Though I can make most things work.

I've always just used ubuntu with i3 because I honestly dont really know what I am potentially missing out on. What is a reason to use something else?

I use windows because that's where I can play overwatch and fortnite. That's literally the only reason. And photoshop, but krita is almost just as good. If I didn't play games not available on Linux I'd probably use Ubuntu instead. Why? Easy to install, very customizable, better for programming, scriptable.
