Well, Arch has (historically) been rather difficult to install from scratch, and requires a lot of Linux knowledge to get up-and-running as a daily driver. If one is installing it for the first time and misses something (which audio backend?), it can be rather frustrating down the line.

There is a reason Ubuntu is usually the first distro new Linux users go to. For almost a decade now, installing a feature-complete Ubuntu setup is not much more difficult than reimaging Windows.
