I use Bunsenlabs and like it a lot

Fedora. Any kind.

Arch (cachyos) on my desktop, Debian on my server.

Doesn’t really get any better than those two in my opinion

Debian Stable. Predictable, low-maintenance, and well-supported. From time to time, I think about switching over to Alpine or even BSD, but the software selection and abundance of Q&A posts for Debian and its derivatives keeps me coming back. Having been a holdout on older Windows versions in the past, I’m quite used to waiting for new features and still amazed at how much easier life is with a proper package manager.

MX Linux is the best, obviously. Otherwise it wouldn’t be #1 on DistroWatch, right? /j

Personnaly, i’m using Fedora and i love it!

I use fedora-based atomic distros for the reliability and security. Nothing else really runs SELinux out of the box and I care about security so that’s a necessary baseline. I roll my own distro though using BlueBuild, and base it off the SecureBlue image of Silverblue. Just using SecureBlue gets you nearly to what I use though

GNU Guix

If there were a universal answer to this, there wouldn’t be any others.

I myself currently use Debian (testing), have for some years now, but I have used other distros in the past too.

Fedora Atomic, especially Bluefin, Bazzite and Aurora.

Nearly unbreakable, very reliable and stable in everyday use, needs no maintenance (updates itself, etc.) and more!

I really love NixOS and use it on all my devices. Its not as difficult as people say and it really makes the linux experience a piece of cake once you get it down.

The single config file to control almost everything is just what I was looking for in linux and the fact that it solved any kind of dependency hell I have experienced in the past is huge. If I had to list a top 3 it would be NixOS, Fedora, and Arch.

I just installed Bazzite about a month ago and love it! Used Ubuntu in the past and it was ok, but eventually went back to Windows. I definitely don’t feel that way about Bazzite though, I think I might stick with it as my primary OS!

I use Arch for personal and gaming, Debian for self hosting and hacking, Alpine for containerized cloud deployments.

I use Gentoo and I love it. The installation process is a bit more complex than Arch but it doesn’t have to be if you choose the precompiled kernel.

The package management is extremely flexible and the community are great. I have a morning routine where I log onto my gentoo desktop before work and update everything; would compare it to raking one of those miniature buddhist sand gardens. Very theraputic!

Arch because I like getting the latest releases of packages
