There’s not a big difference in prestige between the two so matching a competitive specialty will be more on you than the school. Many match primary care at Davis due to personal desire since Davis selects for students like this, similar to UCSF, but it doesn’t mean you won’t have all the resources to match a competitive specialty if desired. Coupled with being closer to home, near family/support system, weather, etc. the cost difference is worth having loved ones nearby. Higher step scores don’t mean anything. Also pretty sure Davis is good with grading on curriculum, iirc they also abolished AOA? Check with current students.
Also, it seems you may want to match back to CA. do not underestimate how difficult this is, even with home ties to the state. Minnesota is not a strong enough school where I’d confidently say, yes you can match back wherever you want. In which case having geographical ties to the state during med school, networking with attendings in the area, plus your west coast physicians will know others in California better who can vouch for you, etc. will be a major bonus.
