NixOS for me. It's a package manager (a very nice, declarative one) that you can use on any Linux (or Mac), and there's also an entire distro based on it.
OpenSUSE Tumbleweed has been my desktop home for the last year. It's very up to date, yet it's somehow solid and reliable despite sometimes receiving hundreds of updates per week. And if anything goes wrong with an update you can easily roll back to a BTRFS snapshot. It has a good repository supplemented by Flatpaks, and I haven't had any problems finding software, yet it's not a hassle like some other cutting-edge distros. It uses KDE Plasma by default, which I consider a plus. I came to it from Mint, which was my go-to distro for a long time, but I enjoy Tumbleweed more for its up-to-dateness and configurability, and I have (surprisingly) encountered more software gaps on Mint.
I'm enjoying what Nix does. That said, the learning curve is very steep, and the documentation is very inconsistent and usually poor.
The repositories for both nixpkgs and nixos are absolutely colossal, which is a huge plus, but their configurations are not listed on the same page, and it can lead to a lot of confusion. Unlike Arch's PKGBUILD, which practically tell the build system exactly what to do, you'll have to learn the structure of current configuration files, or the more recent flake system, to setup things how you like.
I’m a longtime Arch user, and would have preferred to use Arch on a particular system, but didn’t want to deal with needing to babysit ZFS packages from AUR.
So, I decided to use Alpine after never having tried it before, and ended up sticking with it. Like Arch, it’s both lightweight and has a capable/sensible package manager, which are the main things that are important to me.
I haven’t had any growing pains from Alpine’s use of busybox/musl/openrc, things mostly Just Work!
Gentoo. It's amazingly customisable, easy to configure and write packages for, has an extraordinarily good wiki (and installation instructions), and is always seeing new and active development.
There is also official binary package support for architectures as of recently too, which makes it easy to mix and match compiling from source and binary packages.
If we allow derivatives, I'd say SteamOS despite being Arch. It's putting Linux in non-technical people's literal hands and it's not a locked down and completely different platform that happens to run Linux like Android is. It's almost designed by Valve to give people a taste of Linux by the addition of its desktop mode, and people that would be modding consoles are now modding SteamOS and learning how much fun an open platform can be. I've seen people from sales talk about their Decks on my work Slack.
Otherwise, NixOS, no contest. It's been a really long time since we've last seen a fundamentally different distro that's got some real potential. For the most part, Arch, Debian and Fedora do similar things with varying degrees of automation and preconfiguring your packages, but they're still very package oriented. We've been mostly slapping tools like Ansible to really configure them to our liking reproducibly, answer files if your package manager has something like that. And then NixOS is like, what if the entire system was derived from evaluating a function, and and the same input will always result in the exact same system? It's incredibly powerful especially when maintaining machines at scale. Updates are guaranteed to result in the exact same configuration, and they're atomic too, no halfway updated system the user unplugged the system in the middle of.
I’m trying out OpenSUSE Tumbleweed on a few personal servers as I wait for Slowroll, I want to get back to trying to get Gentoo running, and I should check out Guix as a server in a VM.
Gentoo having a binary option should help since I seem to mess up the kernel part of the installation.
DietPi! It's one the most resource efficient distros that is easy to set up. It's ideal for single board computers and virtual machines, so I use it as a low-overhead Docker host on my Raspberry Pis. The dietpi-software tool installs optimized versions of most software you might use for SBC projects, but if it doesn't have what you're looking for, you can also use APT to install packages from the Debian ARM/ Raspbian repos.
Bazzite. It's based on Fedora uBlue so it's technically Fedora, but being an immutable OS, it works quite differently enough that it counts as its own distro. For instance, you don't use dnf or yum to install stuff, you'd use Flatpak/Distrobox/Nix. Updates are done using the rpm-ostree command, and it's effectively a rolling release model, but atomic in nature so you get none of the instability that you'd get in a typical rolling release.
Some of my favourites are Void Linux, Artix and Opensuse Tumbleweed
Void was my first non-systemd distro, and it was super snappy as well. Some packages may not available but overall I had a really great experience with it. It also offers a version with the musl C library. Pretty cool if you ask me.
Opensuse tumbleweed is an overall a great distro, it's one of my favourites. Also I noticed that many people have recommended it and that's for a good reason. It's installer isn't that user friendly but I would prefer it over Fedora's installer any day. ( I haven't tried the last 3 iterations of Fedora, so it might have changed now )
Artix is well... arch with different init systems. Nothing too crazy. Its what I have been daily driving for the past year or so.
I really enjoyed Solus Linux but the last I checked, it didn't support something I need for my job. So, I do use Arch, but was completely smitten and impressed with their impressive boot speed. From pushing POST screen to desktop, it was something like 5 seconds. With Arch, after POST, maybe 10-15 seconds.
With their recent drama, it's been a bit hard to see them struggle. They just did release a fresh build I read online, so they are still alive. :)
I get that there are a lot of novel are cool distros out there, but I just stick with Debian (or one of the other well known distros that have been around for decades).
I do it because from a security standpoint, they have my trust. Maybe in 10-20 years with a good reputation and history, but it's not there.
Gentoo for the documentation, but for a modern comp with bad bootloader implementation, Fedora's anaconda system for the secure boot shim is irreplaceable and my daily. I won't consider any distro without a shim and clear guide for UEFI secure boot keys. In that vain, Gentoo is the only doc source I know of that walks the user through booting into UEFI directly with Keytool.
I think functional distros like Guix or Nix are just another thing. Their ability of programming , provisioning and deploying software environments is unparalleled. My personal favorite is Guix since, while having less packages than Nix, it has the most consistent experience: everything is in Scheme from the top to the bottom of the distro. Also it pushes really hard on a sane bootstrapping story while allowing for impurity through channels like nonguix .
The main downside is the lack of tutorials and a documentation that's very intense, let's say. typical of GNU projects. I suggest the System Crafters youtube channel which has a lot of nice tutorials
MX Linux only because I have it on some very old 32 bit laptops and it supports 32 bit. I don't really know why I keep those laptops around but they are functional.
I really enjoy ZorinOS! I've been using ZorinOS 16.3 and am awaiting the upgrade to 17 through their tool. It's been great for a PC that has an Nvidia GTX1060 that I have hooked up to my TV as a twitch/YouTube/Netflix box. I chose Zorin because they claimed to get the Nvidia drivers installed correctly "out of the box", and they delivered!
Alpine was the most interesting for me. It goes against the tendency of complicating the systems.
I have to use Arch because everything can work on that distro.
Tiny Core OS, because I want a super light distro to run from memory when trying to access computers where the data is still there but something went sour with the OS
not sure if it really counts but I like Universal Blue, specifically using their silverblue-framework image because it already has all the drivers and stuff set up for my Framework laptop
LMDE, MX, Ubuntu etc are based on Debian. Mint is based on Ubuntu, so Debian. Chimera/Endeavour are based on Arch, etc.
In the linux world, you have a linux kernel, systemd or init, a bunch of gnu utils, a window system like X or Wayland, whatever DE you want (Xfce, gnome, kde, name it) and a packaging system (apt, yum, pacman), but for me, it's all the same.
If you want something different, try a BSD distro then? FreeBSD, OpenBSD, GhostBSD, etc
MX Linux. It's exactly how I'd set up Debian if I wasn't too lazy. Although, I've gone back to Debian after Bookwarm was released. I love it but miss MX
Been using Xubuntu 23.10 recently, but I'm kind of a distro hopper. I need ROCm and some other special (proprietary, ehh) tools that require RHEL, SLE, or some Ubuntu flavor. I also like having a working out-of-the-box configuration. I've used openSUSE Tumbleweed and Arch Linux before, might try it again but it's a little bit complicated to me.
The worst documentation of a linux distro I have ever encountered, but the declarative model has convinced me I don't want something else. Now I'm just waiting for other distros to pop up that are declarative as well. (Guix? No thanks, I'm not a fan of endless parentheses)
