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)
No software worth its salt offers only flatpak installation. I don't use flatpak at all and Blender works flawlessly. I'm not sure what a flatpak version could possibly do any better than the version I use.
The official OBS flatpak supports more codecs and integrations than some distro packages.
Stability is also a factor, especially on rolling or cutting edge distros. Fedora RPM release of Blender did not work for me at all with an nvidia GPU, for example.
No flavour of Linux works well with them. That's the joke or something.
funnily enough, i see it as one of the advantages of arch, and a reason i'll keep putting up with the constant updating for the forseeable future - nvidia support has gotten way better recently, and since arch has very recent packages i haven't had nvidia issues in quite a while now.
Once it all lands in debian i'll consider giving debian another shot on desktop... but that'll take a while.
Debian SID?
But we're not talking about rolling or cutting edge distros. MX is based on Debian Stable. Also last time I checked (about a month ago) MX Linux does support Flatpak. Also also, you can enable systemd if you want, but seeing as we're talking about a distro for complete beginners, I don't think they're going to notice, know, or care. Also also also, I really don't care enough about this to drag it out into some protracted argument.
Download ventoy, slap a few distros on a usb stick, try them, use what you like.
