It's not going anywhere. Debian existed when I was a kid and it'll probably still exist when I draw my last breath.
I know how to use it, since, once again, I've been using it since I was a kid.
It has all the desktop environments.
It fully supports systemd. I do not miss the unreliability, slowness, and complexity of what came before that. (Normally I wouldn't mention this, but your former distro of choice exists solely for the purpose of not having systemd, so it's relevant this time.)
Arch Linux. Always very up-to-date and the AUR is huge. No dealing with PPAs or snaps or flatpaks or appimages. Just paru -S any-software-ever-made. Also very streamlined (systemd for everything lol) and well documented. I tried NixOS for a bit but it was very inconvenient in comparison and I felt like it was impossible to tinker with or understand if you weren't good at Haskell. Terrible documentation.
I've been a daily fedora user for the half year. Initially I started off with ElementaryOS but it was so filled with bugs, and glitches, so it didnt last for more than a couple of months. While the fedora experience is way more streamlined.
Been using NixOS for a couple months. It’s gotten easier to configure and change because of it, and new computers are super easy to setup because I can just change/apply the config and system wide changes will apply with one command!
I fall firmly in the Ubuntu/derivative camp for the most part. My laptop is on Pop, some of my virtual servers are on Ubuntu. Only exception is UnRAID, which is technically Slackware.
I used to use Void as my main distro, but then the developer drama made me shy away from it (keep in mind, this was like forever ago and I haven’t looked at Void at all since). After that I floated around trying everything, from Gentoo to the BSDs (I know, not Linux). Nowadays I use OpenSUSE Tumbleweed. I got tired of doing everything manually and OpenSUSE just makes everything so much easier to use, IMO.
I use Debian for my docker servers. I try to use it on the desktop. Was using pop-os, games kept crashing, replace with arch? Archinstall wouldn’t work. Back to windows I guess. Maybe I should try Debian on the desktop since it’s the only one I ever get working properly.
I distro hop a lot. After using Majaro (gnome) for a long time I switched to Pop_OS for a long time. I switched back to Manjaro (Gnome) again, but after a week of use I've just downloaded Ubuntu.
I'm getting basic display issues that I've never got in another distro (including tails!) and it's generally annoying me. I'd rather use a distro that doesn't require troubleshooting on Day 1
Using Garuda (basically just Arch with some bloat) because I'm 1) too lazy to install Arch myself and 2) on an Nvidia card and Wayland WMs still seem buggy for me. Once (if ever) Wayland is stable on Nvidia I'll probably look for an alternative
I use EndeavourOS with Hyprland on my laptop but I am considering trying VanillaOS (once they move to Debian base). On desktop I have Ubuntu 20.04 and EndeavourOS (both on Gnome)
I'm a opensuse tumbleweed user on my desktop and laptop. I also have an ubuntu home server.
I really like tumbleweed, but I have been thinking of switching to an immutable distro like guix or nix. I've tried guix several times and found it pretty good, but never stick with it due to its lack of KDE plasma support. Maybe I should give nix a try.
Ubuntu or Kubuntu. Long are gone the days where I used to tinker with different Linux flavors.
Fortunately, I can afford powerful enough systems so I do not have to be worried about optimizing every single aspect of the OS.
I want things just to work out of the box. I am aware that this applies to more distros than Ubuntu, but I just do not have the time and energy anymore.
Arch on everything, including servers. It's just so easy to install everything via the AUR & configure everything easily. Plus the wiki is amazing. Although it is a pain to setup sometimes
Been using PopOS for my living room AMD GPU pc, and it’s been the most seamless steam machine experience I’ve had so far. Tried multiple distros on my Nvidia one, and I just had no luck, I’ll move my Nvidia pc into Linux soon for another attempt.
Arch for my personal life as it is minimal but robust once you get over the fear of messing things up and level up your skills, and Debian at work since it supports most things and is a stable non rolling release. And KDE Plasma as DE on both.
Manjaro. I am a guy of habits, so I never really distro-hopped, I once tried to install Arch and failed to configure everything so I tried endeavour and failed too (which would mean I am not a tech guy either ;).
Ultimately, I'd say that the distribution does not matters much once you are used to it, you can always get what you want from any of them. The only thing I really like in comparison with others is pacman :)
I use Manjaro, but I run it like vanilla Arch (for example pacman/yay and not pamac). I find this to be a sweet spot for me - rolling releases are so incredibly nice, and Manjaro being slightly slower than Arch is good from a stability standpoint in my experience.
I use ZFS all over the place, including the root storage pool on my home server, which has overall been a great experience with systemd-boot.
Been switching between Arch and Linux Mint for a while now. I run Arch and EndeavourOS on my laptops (Arch on my daily 2-in-1, Endeavour on my TV laptop) but I can't decide which is better for VR on my main rig... probably because VR on Linux is kinda in a pathetic state anyway lol. Next week I'm getting a second GPU for simple display-out so I can use my 6800XT to run VR in a Windows VM, probably on Arch
Edit: landed on EndeavourOS, basically just Arch with a GUI installer, DE by default, and some other tweaks. It's what I kept turning Arch into pretty much lol
Fedora. Used to use Arch but it broke and I moved to Fedora, it's a way more polished experience. I like how Fedora is stable but not "stale" like Debian. Want to try Fedora Silverblue as well.
Xubuntu for over ten years now. It was the first thing I landed on when in a panic that my store-bought, WinXP -preinstalled PC was failing and I couldn't afford to be without it nor replace it. Even after being so grateful for it rescuing me, it's also taught me, and worked flawlessly for all I need from my computers since.
Linux Mint for desktops/laptops (Cinnamon if the hardware can handle it, MATE if it's a bit long in the tooth), and Debian for servers.
I've used several distros (yes, even Arch btw) through the years but I just keep finding myself coming back to the Debian-based ones. I guess I just feel most at-home with the way it has things set up, or something.
Mint with Cinnamon is my daily driver on my desktop and laptop for almost 3 years now. I ran a company for a while using Linux and managed to find everything I needed for software to run administration. It was great. I still have a windows tablet for troubleshooting and equipment specific requests, but I always feel weird logging into it.
I've used Mint since I started using Linux, and never had any major issues. I've therefore just stuck with it. I don't always have the time to tinker with my machine if something should break, and Mint usually just works when I need it, while still providing flexibility when I want it (and Timeshift to fix it when I break stuff)
I wish Arch could be installed everywhere. My Desktop PC, Laptop and Raspberry PI 4 use Arch Linux while my Server used to run Rocky Linux but is abandoned and my Chromebook Duet 3 uses Debian 12 with KDE. I think I could easily install Arch on it after having my Kernel compiled and working with debian.
Currently...
Slackware on main laptop.
Slint (Slackware-based) on mini-pc.
MX Linux (fvwm respin), Void, and OpenBSD on old laptop.
NsCDE is desktop on all except MX.
My laptop is on Manjaro and has been running flawlessly for years ...such a great experience with gnome 40+
My desktop is also on Manjaro, and things could not be more different. No Wayland, no animations in the gnome desktop, visual glitches since the last update ...guess it doesn't play well with Nvidia drivers. Anyone managing something decent with gnome+Nvidia?
I find that bugs in linux programs (and they will happen regardless of distro) are more easily tweaked in systems that do minimal modifications to upstream programs and keep them updated regularly with what the developers release
Also AUR makes it easy to install pretty much anything without having to add ppas, new repo links, etc
I used cinnamon/debian for a long time on my desktop and gnome/ubuntu on my laptop. in the last couple years i switched to KDE plasma/manjaro on desktop and gnome/manjaro on laptop
its nice, for the most part and gives me access to the aur
I have a general use server running ubuntu server atm, i'm considering completely redoing that and havent decided on the distro i will use yet. I want to use kubernetes to sandbox its various uses apart and in a redeployable way so whatever works for that
Fedora Workstation, I'll probably switch to Fedora Silverblue one day whenever the transition is easier for my setup without having to layer lots of extra packages or mess with the immutable system.
