Louis by knockout. prime for prime, i still see joe louis beating him. so this would be easier for louis.
Louis would knock him out, he'd counter him coming in and establish the jab. Joe would begin to take over the fight mid rounds and stop Mike in the 9/10th round. A prime for prime match up would be better.
You would be verry unwise to pick 96 Tyson over any all time great and perhaps any top 30 all time heavyweight.
