The soviets stopped the German general offensive aimed at Moscow in 1941, stopped the German offensive aimed at Stalingrad in 1942, and crushed the German army at Kursk in 1943 and delivered the killing blow with Bagration in 1944.
There is no silver medal in war, it's the ultimate "only the results matter" contest.
At every turning point of the war on the eastern front the Soviets won and came out of the war a superpower.
At every turning point of the war on the eastern front GERMANY LOST and didn't came out of the war at all.
I find it hilarious that you say that the western allies were so much better… despite the fact that on the Western front, and on the western front only, AT EVERY TURN GERMANY WON.
Everyone fap on Normandy (where a force fighting with overwhelming numbers and completely outgunning it's adversary, with complete naval and air supremacy, got trapped for months by literal teenagers and old guys) but everyone forgets the everything the preceded it (you know the ones no one makes movie about…).
First was France and friends that got completely obliterated.
Then the Afrika "Corps" (read 2 divisions) managed to keep the most of the remaining commonwealth occupied and in fact even somehow succeeded in forcing Britain and the leftovers of France in concentrating every soldier and vehicle available of their vast Empires to defend Egypt, and then continued to be a major resource drain all the way to 1943.
And after that Italy… During which the German Army Group C delayed the allies right until the end of the war as they were still far from the Austrian border when Berlin fell despite being back-stabbed by the Italians.
Did they?
They never actually managed to destroy a significant German fighting force which were almost systematically able to withdraw and regroup.
The western allies took far less casualties than the soviets in the process, sure… but so did the Germans, they never managed to actually neutralize the Germans even after their victories.
The Germans never threatened Moscow after 1941, never Stalingrad after 1942 and had lost the war after Kursk in 1943.
Those battle were extremely costly in lives but they were actual victories from which the German army simply couldn't come back from.
Meanwhile on the western front just imagine what would have happened if just 70% of the German army was occupied fighting the soviets instead of 80% at any point of time.
-The Germans would have had an extra division to give Rommel, he would have won Egypt.
-The 10th army would have had reserves in Salerno and repelled the landings.
-There would have been a bit more mobile units in Normandy meaning the German counter attacks on the beaches would have likely succeeded.
-The Germans would have managed to pierce in the Ardennes and trap most of the western allies armies.
Meanwhile Rommel's two divisions wouldn't have changed much in 1941, Stalingrad was lost because too many troops were actually sent there (and the road networks couldn't support it), if Italy had really committed + all of the army group C was available maybe Zitadell would have worked, but it was already a gambit in itself, more troops for Bagration would have maybe saved the Army Group Centre from near complete destruction, but it wouldn't have changed the battle outcome.
