The rationale for one-user ("unique") groups is described in the
manpage for adduser(8). The gist of it is that your users can then
run with umask 002 safely; shared directories for people who need to
work on the same files are then convenient to use, because it's not
necessary to switch umasks when working in the directory or to chmod
all of the files to g+w.
If you're an ISP or something, and you don't have users working on
shared projects, the advantages will be small or zero, though.
