OK so I did some digging - MSP gets top prize for airports in North America serving 25-40 million passengers. IND did win for best in North America for all airports over 2 million passengers (tied with JAX?). Not trying to hate (too much) on MSP, but it didn't make the list of 11 2nd or 3rd place finishers in that broader category. In the category that MSP did win, there are a total of 9 airports that fit that description:

Orlando International Airport
Benito Juárez International Airport
Newark Liberty International Airport
Minneapolis–Saint Paul International Airport
Logan International Airport
Detroit Metropolitan Airport
Philadelphia International Airport
LaGuardia Airport
Fort Lauderdale–Hollywood International Airport

Most of these places are dumps. (full disclosure, I've never been to Mexico City, so I don't know about that one). But vs. LGA, EWR, PHL? It's not like the competition is that tough. Personally? I would rate DTW higher on the list as a transit hub. I can't really judge landside on either. MSP is definitely a close second though.
