Welcome aboard the RoadTrip America Forums!
The difference between the two routes, in both mileage and time, is so minimal that it really shouldn't be the decision maker for this RoadTrip. This is a four day drive either way and the 3 mile/1 hour difference could easily be eaten up in traffic or construction delays. For what it's worth the route through Albuquerque is minimally shorter, but again this is a trip that needs to be thought of in terms of days and both routes are basically four days long.
