Which open source IDS is easiest to observe logs and create rules?

Which among snort, Suricata and Zeek(Bro) is easiest to use. Which one provides parsed and mapped data using which we can analyze logs and create rules. Snort provides logs in terms of packets which is pretty much useless for me.

Edit: Does any of these provide parsed logs
