Fedora:

Fedora is a community-supported distribution sponsored by Red Hat. It often includes the latest software and technologies, making it a good choice for developers and enthusiasts. Fedora uses the RPM package management system.

Debian:

Debian is known for its stability and reliability. It serves as the foundation for many other distributions, including Ubuntu. Debian uses the Debian Package Management system (DPKG) for software installation.

Arch Linux:

Arch Linux is a rolling release distribution known for its simplicity and customization options. It follows the "Arch Way" philosophy, providing a minimal base that users can build upon according to their preferences.

openSUSE:

openSUSE is a Linux distribution sponsored by SUSE. It offers both a rolling release version (Tumbleweed) and a more stable release (Leap). It uses the Zypper package manager.

CentOS:

CentOS (Community ENTerprise Operating System) is a free and open-source distribution derived from the sources of Red Hat Enterprise Linux (RHEL). It aims to provide a free and open alternative to RHEL.

Manjaro:

Manjaro is an Arch Linux-based distribution that aims to make Arch more accessible to a broader audience by providing a user-friendly installation process and pre-configured desktop environments.

Linux Mint:

Linux Mint is based on Ubuntu and Debian and is known for its user-friendly approach and out-of-the-box multimedia support. It comes with the Cinnamon, MATE, or Xfce desktop environments.
