Which distros should be avoided in your opinion?
Discussion
This is probably subjective. Many people hate Ubuntu based distros for various reasons. If you're a beginner you'll hate Kali or Arch Linux. Red Star is probably bad 😂 That's the North Korean distro. All of my servers from the late 90s and early 00s were Slackware. I'd probably not recommend that now as it seems not as popular.
I used freebsd in the 90s and early 2000s. still think bsd is better than linux :-D
