To be fair, I would see why. Arch isn't that hard to install anymore so some people see Arch-based distros that are just Arch with GUI installer as useless. I use EndeavourOS just because GUI installer is more convinient to me.
Endeavour is objectively better than plain Arch, this list is incredibly subjective.
Edit, according to the reply chain below:
My point applies when the desired result of an install is a day-to-day general-purpose OS on a modern (201X+) system. Where the savings of plain Arch versus Endeavour aren't noticeable.
Have you actually tried Manjaro or do you just listen to what other people say about it? I find it has no issues and have been daily driving it for like 3 years now. Just because something has negative hype doesn't mean it's as terrible as people say.
This website has a good summary of the problems with manjaro https://manjarno.pages.dev/ . I've used it too and it's usable from a user perspective, but it has so many underlying issues
I'm fully aware of the issues, but they've never impacted me personally and I'm not much of a distrohopper. If it ever borks my PC I'll probably switch.
GuixSD in tier-3? It uses the same tech as NixOS - store-based hierarchy, and functional, transactional package manager. The only thing that's different is the language - Guile Scheme is functional, acts as a convenient way for REPL as well as debugging the system, and eliminates additional scripting dependencies, while also being great for meta-programming. One language to rule them all. And yes, uses Shepherd instead of systemd. Want more GNU in your GNU/Linux? Guix is the thing. You can also probably boot using Hurd, but I've not tried that out.
I will not complain about the rest of them because I've not used them well enough. But I know that this tier-list is just bad. ClearLinux has a really good package manager - perhaps, the fastest of them all. And the rest of them are well, based on a root distro, and good for their specific use-case. Debian and Arch is also used for testing alternative non-Linux kernels. Alpine offers musl C instead of libc and Busybox instead of GNU coreutils+/-binutils.
