This looks like it comes down to a location preference. ICOM and UIWSOM both cost 60k, ICOM has slightly higher pass rates, and both have decent match lists with the edge going to ICOM.
ICOM is in meridian/Boise and UIWSOM is in San Antonio. So both urban/suburban. Maybe choose the one closer to a potential support system or if you prefer the weather of Texas vs Idaho.
You can take a look at this years/previous years school specific threads and see if any students gave their perspectives on the schools.
If I were in your shoes I would go with ICOM. Seems like a good school and its closer to home.
