> The main thing that people like about it is the rolling release model; new packages for virtually everything are updated within hours or days of an upstream release, with incredible practical stability.

Fedora Rawhide and openSUSE Tumbleweed are both nearly as up-to-date[1] as the Arch repos but they have package managers with correct dependency solvers and continuous integration pipelines with tests produce their repos. NixOS Unstable is more up-to-date than Arch Linux[1], and its package manager never breaks your system on upgrades and features automatic rollbacks no matter what filesystem you use.

‘I want a rolling release’ doesn't really explain the choice to use Arch in particular, imo, and it's weird that this extremely common answer to ‘why Arch’ talks about a feature that isn't really specific to Arch
