Pro Streaming service integration (under development)

Pro For entertainment, it just works

Pro No systemd
Artix actively supports the runit init system known from Void Linux. (Equally besides the OpenRC init system known from Gentoo).
Pro Compatible with Arch Repositories
It is fully compatible with almost all packages from community, extra, multilib and AUR.
Only the software you would need like Terminal emulator, file manager, media player and a browser.
Pro Close to bare Arch Linux
No learning curve if you're coming from Arch or any of its derivatives.
Pro Rolling distro
You can have a functional system in less than 10 mins using GUI installer OR you can do it "the Arch way".
Con Not built around the desktop experience
SteamOS is, first and foremost, meant to act as a gaming console - it doesn't ship with even some of the most basic applications, such as a file manager or image viewer. As a result, using SteamOS as your primary operating system would require a fair bit of work.
Con Hard to install
If you've installed Arch you're probably fine, but for those used to simple installs like (Ubuntu to name just one) you should prepare some patience, determination, and painkillers. Good news is, it's getting better (it's very young).
Con No systemd
Some packages flat out won't work because systemd is non existent, sadly pipewire needs systemd to run. Hopefully Pipewire becomes usable soon. Edit: Pipewire does work but you will have to make a startup script.
Con Few Arch packages might not be available yet
Developers are working migrating all packages into their own repositories while ensuring there's no systemd malware.
