As the monthly notice says, these are the same thing. Only send to
one.

This TOTALLY depends on your maintenance structure. Who can change IP
addresses? If you think they are likely to change prometheus.com [or
do you mean hephaestos.prometheus.com?] to have another IP address,
then leave it as an A. If you think you are, and they'll have to
follow you without notice, then make it a CNAME. Otherwise, flip a
coin.
There is a reason that you can do things multiple ways. So you can
find the best way to do it for your purposes!

Your choice! Always, your choice!
