So whats really recommended?
It depends :-)
If Your SRX cluster is SNMP-polled via same IP (such as IP on loopback/lo0) and want Your SRX cluster to be represented in SNMP as one logical entity, use same engine-id.
If Your Routing Engines in same SRX cluster are polled separately via different IP (such as IPs on fxp0) then use different engine-ids. Why would You want to poll SRX cluster' REs separately? There are several reasons, most common is to always make sure backup node RE is healthy and ready to take over. Some of the backup RE metrics are available by polling master RE but not all.
