Maybe a positive/less divisive way to look at the two colleges is this: Emory is the U, while Oxford is the LAC. I imagine two years at Oxford could give a student a pretty broad lib-arts base to take to the main campus for the upper-class years.
It’s an interesting setup and I imagine (further) that a lot of kids who may have been disappointed initially with their Oxford acceptance end up benefitting greatly from it and being grateful for having been given the opportunity to receive that sort of hybrid LAC/U education.
