The defeat of Leningrad would have been easier than Stalingrad.
The loss of Moscow would have been much greater loss than Baku and resulted in a shortening of the front of which a latter southern drive could succeed without fear of getting cut off because at that point all logistical support for Soviets would be coming entirely east of the Don and this country is not too developed. The last Soviet Factories would be in range of Axis bombers and the front would have rolled up more easily, than committing the 6th to Stalingrad with all other Soviet logistical and political objectives are intact allowing easy reinforcement from rail heads running south from Moscow.
