1) Reporting (CJA)
Orchestrated campaigns write message feedback, tracking, and journey-step events as XDM Experience Event datasets into AEP. CJA can create connections on top of these AJO datasets and expose them via a data view for reporting.
However, datasets created using relational schema types (used by orchestrated campaigns) are not compatible with CJA connections. Therefore, reporting on orchestrated campaign relational datasets is not possible.
2) Onsite Personalization (Adobe Target)
Using the Save Audience activity in the AJO orchestrated campaign canvas, campaign-orchestration-type audiences can be created. These audiences can be shared with various destinations, similar to custom upload audience activation.

3) Personalized engagement (AJO Offer Decisioning, personalized email/sms/push etc)
Personalized engagement is possible via email, SMS, and push channels.
However, Orchestrated campaigns do not support Offer Decisioning capabilities.
