No.
Mint works ootb but that is just one criterium. People can help you with setup. What about
- breaking with upgrades or needing an at least medium savvy user to do them
- lacking behind on updates
- incompatibilities with Ubuntu that occur
- upgrades not being enforced-ish so noobs dont care and dont upgrade (I know more than 2 people like that, you are in a bubble if you think manually upgrading is something that people do)
- flathub being preinstalled but only verified apps are there, instead "unverified" deb packages are promoted that are not sandboxed and behind on updates
- desktop looks ok but kinda ugly
- apps same, subpar to KDE
- X11? I hate when people like LTT think that this outdated stack is what we currently have on Linux. I hope they can get the wayland session going but Cinnamon will always be behind GNOME and KDE
why should an underdog nieche distro with ¼ the maintainers of KDE or GNOME (rough approximation, may be way worse) be better for beginners than the actual standard?
