This is indeed the safe behavior, and then the two approaches would be
equivalent. However, if you use the DAEMONS array you have the
flexibility (if you know what you are doing) to optimise it (a lot).

Essentially the only thing you need before kdm is dbus (maybe also
syslog-ng). I run with
DAEMONS=(syslog-ng dbus @kdm ...)

If you run a service that relies on the network being up (ssh, netfs,
...), then you need to block on the network daemon, which might take a
long time to start. However, it might not be necessary to start kdm
after network, so we are loosing a lot of boot time for nothing.

As to the problem of a broken system: This is what single user mode is
for. No need for a livecd.
