The short answer is that dd operates at a lower level than cp. If you
thoroughly understand what you want to do, and how to tell dd to do it,
then you're okay using dd. Unless dd can't easily do what you want.
Using cp, you're going to be okay. It'll easily handle the differences
between filesystems, or whatever. So I certainly use cp unless cp can't
handle the job (like copying things that aren't files, like the MBR).
It's just plain easier and less error-prone to use cp.
