The up2date in CentOS uses a yum backend to retrieve the files anyway
(though it uses an older version of yum than is included in CentOS-4).
For updates only, up2date is very simple for users with a GUI, which is
why it is included.

yum is more for all package management (install, remove, updates), and
it can do updates easily from the command line.  I use yum exclusively
on server machines where I don't load a GUI ... but I have to admit that
I also use up2date on my main workstation :)
