I took 24 this summer after visiting in the Ann Arbor area. It was a good decision. Near Toledo, there is come construction, but after a few miles, it is a nice, scenic highway with moderate traffic. Nearer to Fort Wayne, it is brand new 4-lane, so new that my GPS thought I was out in open fields. A bit of construction right at Fort Wayne puts you on local roads for a couple of miles. The new construction is really smooth.
I would use 24 again.
