No advantage, unless you're migrating Window$ users to Linux and believe
that a text login would result in serious brain damage.
KDM, XDM and any login manager out there has to be suid root. It also
runs as a service (i.e. continuously). Contrast that with the first
rules of linux/UNIX security - thou shalt turn off any unnecessary
services && thou shalt minimize the amount of suid binaries on your
system - and you have very good reasons to get rid of graphical login.

edit /etc/inittab and change
id:5:initdefault: (default runlevel is 5)
to
id:3:initdefault: (runlevel 3 - i.e. no login manager)
