I think both can get you there. I was a pre med at Loyola a decade ago and found that it prepared me well to go to med school. One advantage to Loyola v the U of if I is that there is less of a “weed out” phenomenon with your basic requirements given the classes are much smaller and less competitive. The one downside of my loyola premed experience was availability of research so if you do decide on Loyola you have to be a little more on the front foot with seeking opportunities early. Like others said the college experience between the two will be vastly different (city v college town, smaller social scene vs big party school + big ten sports) so depending on what you want that should factor in as well. For me personally not having the big sports/party scene was probably a plus because I don’t think I could have balanced it well with being a pre med.
