I would first bring my choices to 2 schools. Lets see.
If you are even thinking about UNC, then might as well prefer tepper over UNC since you dont have scholl from either. So among these 2 schools, lets remove UNC for the time being since tepper is way better when it comes to consulting/ranking/MBB placements.
Now among, owen and olin; i would place both these schools at par although olin enjoys better placement percentage(almost 96%) compared to owen(90%). But i dont think its that big a difference to force you choose olin over owen. Owen is an upcoming school and is on the rise and is located in Nashville which is a wonderful place to spend your 2 years compared to St louis. So aomng these 2 schools, i would choose owen, provided you have full rides from both these schools.
Now, the equation comes down to Owen(full ride) vs Tepper(no $). If you are a die hard fan of MBB and want to just get into these firms, then you might as well give tepper a try. But if you are ok with Deloitte/Pwc, I think you wud do great at Owen.
Plus at tepper you will have a bigger class than owen so if you are a fan of smaller class, then owen is the school for you.
