shadow and util-linux have a lot of overlap. Fedora has historically
used util-linux for as much as possible; Debian has historically used
shadow, but is gradually moving towards util-linux because in practice
it's more actively maintained; other distributions I don't know. The
major user-visible difference has usually been differing su behaviour.

In Debian and its derivatives there are certainly different rules. useradd
is the mechanism layer, and adduser is a Debian-specific policy layer (for
instance adduser rejects weird/inadvisable usernames unless given an option
to force them).
