Different distros are better at different things. Need a stable distro for your grandma? Use Debian or Mint. Need latest software? Use Arch or Gentoo. (And people do need latest software sometimes. For playing games, or in my case, for doing research. The F is FOSS stands for Free after all.) Similarly, there are server distros like AlmaLinux tuned for high reliability. I think it’s counterproductive to argue about the “best” distro.
I guess the meme technically doesn’t say that Mint is the best, but it kinda gives off that feeling by ridiculing Arch users.
