All clogMessageGenerated notifications from devices should be properly decoded by the management station. The entire message is encapsulated. Whether or not processing messages using the syslog-to-trap encapsulation is more useful that the syslog itself depends on your management station. I happen to think RME (4.x in any event) does a good job with processing syslog messages and turning them into external actions.
Since the trap breaks out facility and severity into separate varbinds, the trap manager also has a good chance of doing useful thinks with the syslog notifications, but this may require more scripting work on your end.
