I did look at snort and actually some people run both snort and OSSEC. I
don't remember the reasons.

Simply put, they're different things. Snort is a network IDS which examines
network traffic packets, looking for the signatures of various attacks.
OSSEC is host IDS which monitors logs for evidence of attacks or misuse on
a host OS. In many installations, you need them both.
