Both were equal to each other.
They both had the same level of technology. They both made progress against the Nazis. And they both committed atrocious and unforgivable war crimes against Germans, including civilians who had nothing to do with the war.
It's argued that Russia had the best ground troops, Britain had the best air force and the US had the best navy. All three combined together is what led to Germany's downfall.
Bear in mind that Russia (the Soviets) were the ones who captured Hitler's command bunker and confirmed his death. But it was the Allies (UK, Canada, Australia, US, etc) which Germany surrendered to. So both Allies and Soviets are equally responsible for ending the war with Germany.
Historians also argue that Germany was the better military overall of those involved in the Second World War.
