Congrats. My D is also applying to Architecture and got into UM and waiting for Cal Poly (I did not know the results have come). Anyway, pls take ranking as a data point. UM is part of a big city. Based on the research I have done Architect tend to stay where they study. So most of the Cal Poly student end up on So Cal area and UM stay in Miami. The arch program in UM provides some good dual degree program which is a good option to look at if your D want to start her own practice down the road.
Bottom line, it is your daughter choice. Both are a good school. Since I got lot of money from UM (which I heard they don’t usually give) I will go there.
