UW Madison has a great program and is very nurturing; the department also has a great deal of research shared with psychology and they have a fantastic CAP MD/PhD who does trauma functional imaging research. Their program director was my resident while I was in medical school and she was fantastic! Really good child consult work too as the childrens hospital is great.
Michigan has a great reputation but I know very few specifics.
NW has a very well known chair (Dr. Dalkin) who I personally like a lot. She is known for liking their tough call schedule (both years) which is a downer for some and unlikely to change as long as she remains the chair. The children's hospital is fantastic, top 10 in the country for sure which by itself adds a lot of pluses to the program.
UIC has a comparatively very light call schedule, good 0-5 program, and a very warm environment. There is a lot of research at UIC in neuroimaging, biomarkers, etc but you would definitely need to be a self-directed to make it happen during fellowship.
Iowa is fantastic, very biologically oriented but fantastic. The city is a bit of a downer unless you like small college towns.
Mayo is grossly overrated in psychiatry IMO. They have much bigger strengths in other areas of medicine. You will get exposure to Saudi royalty if that's your thing but I think most midwestern university programs are stronger.
