No, not even close. The theory of Nazism and Communism as "twin evils" originates with Double Genocide Theory, a form of Holocaust trivialization and Nazi apologia. The USSR was a dictatorship of the proletariat, those oppressed were the Bourgeoisie, Tsarists, and the Nazis. It isn't a matter of simply saying "socialism," it's taking an honest look at history. In reality, there is no comparison to Nazism, which invented industrialized murder and sought to colonize Europe and the world just as Britian, France, Germany herself, and other Western countries had done to the Global South.

I suggest you read Blackshirts and Reds.

Declassified CIA report:

Even in Stalin’s time there was collective leadership. The Western idea of a dictator within the Communist setup is exaggerated. Misunderstandings on that subject are caused by lack of comprehension of the real nature and organization of the Communist power structure. Stalin, although holding wide powers, was merely the captain of a team and it seems obvious that Khrushchev will be the new captain.

A lot of the cold war propaganda about the USSR turned out to be bullshit, as contemporary Western academic historians will tell you, including Domenico Losurdo.
