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)
I know someone who was fed up with Windows recently, and they decided it's finally time to switch to Linux. Me and another person recommended Linux Mint, but they got many other recommendations for Arch. They went with Arch, and it hasn't gone boom yet, but I'm not sure if it's a matter of time or what.
I have heard Arch is more "stable" these days than it used to be, but I'm not sure.
I use Ubuntu myself except for on my ThinkPad where I use Mint, and I'm gonna switch to Mint on my desktop eventually.
Once it's installed Arch is just as easy to use as any other distro. It's "unstable" because it's rolling release, sometimes issues crop up with bleeding-edge updates, just keep an eye on the forums before updating.
I've only had to deal with a broken system a couple of times, both were 100% my fault, and both were fixable without reinstalling. Even when something breaks it's pretty forgiving, as long as one is paying attention and not afraid of reading documentation.
So to me, that sounds not ideal for someone new to Linux.
Depends on the person. Someone who just wants a stable desktop that works? No. Someone who wants to learn how Linux works, and likes to tinker? Yes.
