RST should be mostly CRJ-900/700, although I know it's had some mainline service. DLH is a mixture of mainline and various RJs AFAIK (also AFAIK the only Duluth with a commercial airport is the one in MN).
EAU would be all CRJ-200 or equivalent, without FC. So I think using EAU would be miserable and it's about a two hour drive from downtown Minneapolis. Maybe it would make more sense timewise from St Paul and points east or southeast.
If you're in the far northern suburbs, I could imagine that driving to DLH would take about the same time as RST, especially during rush hour. Duluth is less than two and a half hours from downtown Minneapolis and Rochester about an hour and a half, so if you can avoid crossing the city, DLH wouldn't be much longer and would have less variance due to traffic.
