Arch is a gateway drug to NixOS
Most Linux users cut their teeth on a "batteries included" distro. Ubuntu, Fedora, Debian, or an equally easy-to-use option is a common way to get started with Linux.
At some point these distros fall short. You may want to try a tiling window manager or desktop environment that isn't offered out of the box, and while you can shoehorn these in, it eventually becomes easier (and cleaner) to build your system up from a minimal base than it would take to bend a pre-configured distro into shape.
