So while the infrastructure may be better, access to that infrastructure is actually worse, as NW's reaccommodation in the event of an irregularity may not be as good.
I've found NW to be really good with accommodating pax on other airlines during IROPS, at stations with few NW options, just my personal observation however.
I prefer DTW for connections (easy, long straight terminal with monorail, moving walkways and nicer WCs), but MSP is also great in dealing with its weather making it a much better choice for me than ORD and much easier to navigate too.
