In my opinion they aren't any less functional. I've even read that
"tar -cpf - /|(cd /mnt; tar -xpf -)" manages to avoid going into a loop
with regard to /mnt! I haven't verified this but I'm not surprised - GNU
software is the way to go!
The con regarding "cp -a" is that it's GNU cp. Versions on other systems
fuck up symbolic links e. g.
The pro regarding tar is, there is one on every system, and combining two tars
with pipes works everywhere (to my knowledge). This makes tar ideal for
scripts that must work on all platforms.

The answer is yes. Both can do that.
