Ranked in these QuestionsQuestion Ranking
Pro No systemd
Artix actively supports the runit init system known from Void Linux. (Equally besides the OpenRC init system known from Gentoo).
Only the software you would need like Terminal emulator, file manager, media player and a browser.
Pro Compatible with Arch Repositories
It is fully compatible with almost all packages from community, extra, multilib and AUR.
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".
As the name would suggest, SolydXK is rock solid Debian.
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.
Con No tiling WM (i3/sway) out of the box
Con Installer doesn't recognise partition table SOMETIMES
On a couple of occasions the installer has told me one of my disks is missing a partition table but it definitely has one and other distros haven't presented this warning.
Con Default theming not to everyone's tastes
The default icon theme in particular is IMHO pretty ugly. Easily changed but if you like to just plug & play without changing themes it may not suit you.
