Arch is aimed at people who know their shit so they can build their own distro based on how they imagine their distro to be. It is not a good distro for beginners and non power users, no matter how often you try to make your own repository, and how many GUI installers you make for it. There's a good reason why there is no GUI installer in arch (aside from being able to load it into ram). That being that to use Arch, you need to have a basic understanding of the terminal. It is in no way hard to boot arch and type in archinstall. However, if you don't even know how to do that, your experience in whatever distro, no matter how arch based it is or not, will only last until you have a dependency error or some utter and total Arch bullshit® happens on your system and you have to run to the forums because you don't understand how a wiki works.
You want a bleeding edge distro? Use goddamn Opensuse Tumbleweed for all I care, it is on par with arch, and it has none of the arch stuff.
You have this one package that is only available on arch repos? Use goddamn flatpak and stop crying about flatpak being bloated, you probably don't even know what bloat means if you can't set up arch. And no, it dosent run worse. Those 0,0001 seconds don't matter.
You really want arch so you can be cool? Read the goddamn 50 page install guide and set it up, then we'll talk about those arch forks.
(Also, most arch forks that don't use arch repos break the aur, so you don't even have the one thing you want from arch)
Debian is the best distro for newbies, it may require setup and reading some documentation but afterwards you get a stable distro.
Stable doesn't mean what you think it means. Stable means not updated.
Oh no! I haven't got the latest push from 30 seconds ago. My operating system is so out of date and I'm so uncool!!11
Nope, you're missing the point entirely. It's about versions not frequency. For example Ubuntu 16.04 used python 2, despite python 3 having been released for 8 years at that time and other distros like Arch having migrated to python 3 years before. Now, Python 2 still got regular updates that Ubuntu released, but Ubuntu 16.04 was maintained until 2021, whereas python 2 reached EOL in 2020, that means that for 1 year Ubuntu was using a deprecated and unmaintained version of python.
One could also make the argument that Arch broke a lot of stuff when they did that upgrade, and there's an argument there, but it's not as simple as receiving less frequent updates.
You're going to be horrified to discover the software versions the military use.
