We came from snort. Here is a discussion we had about the switch from snort to suricata: Suricata on NethServer? @filippo_carletti can tell you more about the process of changing from snort to suricata.
Most important feature to choose suricata over snort: multi thread (cores) support.
long story short: at the moment suricata is supported and not snort.
instead of installing the IDS (suricata) module, you still can install snort by following the (official) snort install guide for centos 7: https://snort.org/documents
