My speculation is that with Kriegsmarine convoy raiding made possible by surface ships in the Atlantic, not just the rudeltaktik wolfpacks, the Soviets may very well have been pushed back beyond the Ural mountains. Moscow almost certainly would have been put to the torch (whatever was left to burn) before being given over the Germans, and we would have seen another RKKA army destroyed in a massive battle of annihilation in its defence.

The most significant Lend-Lease aid was not warplanes (Such as the P-39 Airacobra or P-40 Warhawk) or tanks (M4 Sherman, once refitted with a Russian 76.2mm gun is apparently quite a good machine until 1943), but rations, bolts of cloth, and trucks. The entirety of Russian industry was given over to producing the weapons of war, to the detriment of the logistics side which needed every Studebaker truck it could get its hands on. Uniforms were made with Canadian and American cloth. Canadian grain and American meat went overseas in tremendous quantities to make up for the lost agricultural potential of the USSR and Britain, as they had mobilized so much of their male population that many farms were down to literally just a handful of people, either not of fighting age or infirm.

KMS Bismarck and similar warships getting in amongst any of the PQs would have raised merry Hell with this. Combined with a solid offensive the East, the USSR might have collapsed. The Germans were very, very good as this sort of strategic-operational coordination and without that flood of supplies through the back door Hitler's idiocy and the fawning retardation of the General Staff would have made up for a large number of deficiencies.

Edit: I just forgot to mention the obvious. ltforce, bloody nice work. A Knight's Cross for you and your crew, certainly, probably with some sort of made up attachment specifically in your honour to go with the oak leaves, swords, and diamonds.
