Well...
When BSD chown came out they allowed user.group to double up
(historically you had to go chown user, chgrp group). However, there
were places with dots in their login names (I recall a uni with login
accounts for subjects like 6.631 and I can well imagine people wanting
logins like fred.nerk instead of the more common fnerk etc). So... When
SysV adopted this behaviour they used the : as the delimiter, which is
robust since it's also the delimiter in the passwd file and thus you
can't specify login names containing colons.
Other than that greater generality there's no difference.
