I would agree with the comment above. It’s about fit. From my understanding which is limited OCU has a wider range of opportunities. Opera, operetta , plays and MT of course. IU would be more strictly MT with some plays. It would be a good fit if you were all MT (and not interested in getting side tracked in an operetta). At IU, opera and operetta is in Jacobs and MT students are not cast presently. My D was able to do MT classes at IU and enjoyed them. She felt the training particularly voice training was good - and that’s while being in Jacobs. But Jacobs (as with all programs) takes an incredible amt of time and opera rehearsals conflict with MT rehearsals. The MT group was tight and really worked a lot together. That can be a positive. They seemed like a very good team. So while my D enjoyed the classes and opportunities, her experience does show how these are separate worlds at IU. She could never really bond with the MT kids bc she was always in opera productions. At OCU I don’t think there is as much separation and specialization. So it depends on what experience the OP wants. I think they are both excellent so 2 great choices.
