🐧 Why are traditional distros recommended more often to newbies than immutable distros?

Whenever a beginner considers switching from Windows to Linux, Ubuntu, Linux Mint and even Arch are the ones usually recommended.

Why aren't immutable distros recommended instead? Immutable distros like Fedora Kinoite are much easier to use because of their centralized store and flatpaks, and they are also far more stable and secure.

Kinoite specifically uses KDE too, which is very easy for Windows users.

Traditional distros are more prone to breakage, and require the use of the terminal more often.
