Most Linux distros these days are based on just three Linux distros. Debian, RHEL, or Arch. Meaning, that a lot of Linux distros are going to be mainly the same besides the desktop and what packages that they get. However, there are still some completely independent Linux distros that have their own package managers and code. I am going to go over 5 of my favorites, and providing a brief explanation as to what makes them unique.
Did you even read the article? They want to show alternatives to Debian, RHEL and Arch. Debian is certainly not an alternative to Debian ;')
I did and it’s misleading. Debian itself is independent.
