If you want the benefits of open source operating systems, this guide compares 11 widely used Linux distributions in plain language so you can choose confidently. In short, a Linux distribution (often called a “distro”) packages the Linux kernel with software, drivers, a desktop, and a package manager to create a complete operating system. The “best” choice depends on your goal: friendly desktop, stable server, cutting-edge development, ultra-light footprint, or specialized security. To get oriented, here’s a quick path to a smart decision: define your primary use case, check hardware requirements, pick a package manager you’re comfortable with, try a live USB, verify driver support and codecs, and then install with disk encryption enabled. Follow those steps and you’ll land on a distro that matches how you actually work, not just what’s popular. By the end, you’ll know the trade-offs, the setup moves that matter, and which distro will save you time.
Package manager cheat sheet (small reference):
| Family / Distro | Package manager | Packaging model |
|---|---|---|
| Debian, Ubuntu, Mint, Pop!_OS | APT (apt) | Traditional repos + optional Flatpak/Snap |
| Fedora | DNF (dnf) | Traditional repos + Flatpak |
| openSUSE | Zypper (zypper) | Traditional repos + Flatpak |
| Arch, Endeavour, Manjaro (Arch-based) | Pacman (pacman) | Rolling release + AUR |
| Alpine | apk (apk) | Musl-based, lightweight |
| Rocky (RHEL-compatible) | DNF (dnf) | Enterprise repos |
| NixOS | Nix (nix) | Declarative, atomic builds |
| Kali | APT (apt) | Security tooling repos |
