Nagios is a "network" monitor, in that it monitors the machines on your
network to tell you which services are up and which are down. It
monitors your service status.

SNORT is a network intrusion detection system. It monitors traffic on
your network, regardless of which host it came from or is destined for,
looking for patterns it might recognize as attacks.

Since they are used for almost completely different things, "best" is
not a meaningful question. SNORT is a very strong NIDS, well regarded by
most users. I have heard that Nagios is a good service monitor, but
there are other alternatives, and Nagios does not have the near-total
dominance of its niche that SNORT does.
