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)
It's a really simple system meant to 'just work' and provides an idiot sheet you can copy and paste from for those who don't ever want to RTFM
as long as the system isn't doing anything important Arch is great for noobs fucking around, it's high grade spoonfeeding and doing what you are told.
Power users use RHEL, Ubuntu, Gentoo. Governments, armies, tech giants and that kinda stuff, Arch is more for newbies karma farming on r/unixporn for lolz
I'm pretty sure "Power users" don't use Ubuntu.
I dunno, I used ubuntu (or some flavor of it) for 15 years before Arch. I will say that the first time I installed Arch, I did it solely to prove to myself that I could. After that, I fell in love with it as a daily driver for a lot of reasons. The AUR is a big one, and the fact that it's so well documented also helps. But really, once it's installed, Arch isn't any more complicated than any other distro to keep running.
I did switch to EndeavourOS, though, because once one has installed Arch the "Arch way" a few times I don't reallly see any benefit in doing it again.
