It looks really good but I wonder if it is as efficient as niri or paperwm https://blog.system76.com/post/cosmic-de-tiling-redesign-and-libcosmic-rebasing

The difference between distros are the package manager and choice of default software and settings.

E.g. Debian has no wifi enabled. Hence, ubuntu (which is like debian) is much easier because it’s user friendly. Ubuntu uses a disliked packaging format, snap, which is not used by mint. That’s why people love mint, becaus it’s as easy as ubuntu and has no snaps. Blablabla

Whenever you want to know some linux thing, read the arch wiki and you’ll know more about it.

Distrobox is like a vm, you spin up a distro within your OS with no overhead and can use arch on debian. Or ubuntu on arch. Or fedora on opensuse, or all at the same time because why not?

I’d try https://fedoraproject.org/atomic-desktops/ or https://vanillaos.org/ and install most apps as flatpaks. Vanilla is like ubuntu but you don’t mess with the underlying system. Atomic fedora is “the same” but with fedora style. Problems arise at the dev level, not the user level. It should be good to go on your system

Mint vs fedora is completely irrelevant here. GNOME vs KDE is more important and fedora supports both.

Which packages can be installed is also completely irrelevant since you can use nix and distrobox and flatpaks on all distros. Package availability is no reason to choose one distro over another.
