Comparison of Linux Distributions

It's a well known fact that there's hundreds of different Linux distributions, with many of them gaining sudden popularity or falling back into relative obscurity. As of 2023, I'd say the most important distributions - those that are here to stay for another decade at least and those that have a significant mindshare on the desktop - are just five: Debian, Ubuntu, Fedora, openSUSE, and Arch. Everything else is more of a niche distribution, be it for servers (RHEL, SLE), nerds and greybeards (Gentoo, Slackware), or to make an existing general-purpose distro slightly more user-friendly for novice users (Zorin, pop_OS).

Distributions mostly differ in their package manager and their default choices (desktop environment and so on). Furthermore, there are clearly different tiers of difficulty from beginner-level to expert, for example like this:

Beginners. Easy to use and work out of the box.

• Ubuntu / Kubuntu
• Ubuntu-based distros like Mint, Pop_OS, or Zorin
• Solus

• Fedora
• openSUSE
• Mageia

• Debian
• RHEL
• Arch

• Slackware
• NixOS
• Gentoo

For this comparison I have focused mostly on "original" distributions rather than forks as there's often only superficial differences between closely related distros. For example, the only differences between Ubuntu and Mint would be that Mint is only available for x86_64, that fewer desktop environments are available "preinstalled" for Mint, that Mint doesn't have the longer update support that Ubuntu Pro offers, and that Mint preinstalls Flatpak instead of Snap.

Appendix I: How different are they and how different have they been?

Since the beginning of Linux, different distributions come with different tools and packages, making it hard for developers to make sure that their applications work on all distributions. The most obvious user-facing differences are the choice in desktop environment (also see here for a timeline of default desktops) and the package formats used. I have looked at the most important Linux distributions for each year. Click on the years below to see what has changed over time. Overall, when looking at the seven categories below (desktop environment, toolkit, display server, init software, package formats, file systems, security modules) there has always been around 70-80% homogeneity across the four big distributions.

Appendix II: Linux distributions' relative popularity (on Distrowatch) over time

The graph below shows the relative amount of hits on Distrowatch for the different Linux distributions, grouped by larger distro families and ancestries. The data is available for 2002-2023Q1. As well all know, Distrowatch hits are NOT a reliable indicator for the market share - just think of the mysterious #1 position of MX Linux - but nevertheless it's quite interesting to see how things have changed over time. The greater Debian family now dominates, although Arch-based distros have also recently gained a lot of popularity. At the same time, Gentoo, Slackware, (open)SUSE, Red Hat/Fedora and Mandriva have lost in the Distrowatch rankings compared to the early 2000s.

How to read it? Like any other diagram showing market share over time. The x-axis moves along the years starting in 2002, and the thickness of the coloured slices along the y-axis indicates the relative amount of Distrowatch hits compared to other Linux distributions. In the large chart at the top, all Linux distributions add up to 100%. In the smaller chart at the bottom it works similarly, with Linux, *BSD, and Solaris/Illumos adding up to 100% and the relative thickness showing the relative amount of clicks of these three OS families. (Note that the two charts are not using the same scale on the y-axis.)
