Well, unless one were Jewish (as the regime took advantage of popular anti-Semitic sentiments, particularly to use against the Weimar Left and the Moscow Socialists) then I don't see why he could possibly prefer Stalinism over prewar Germany. Some intellectuals were slow to see that the Red Star had lost it progressive luster almost from its inception, but the question is conducted with the benefit of hindsight here.
Most people forget that Marxist-Leninism had decades to develop yet we judge Nazi Germany by today's standards and not the normative standards of the 1930s, which we have often ignored or actually even tried to erase from our own feel-good history. The democracies in those days (if they were weak) could not do anything to protect their ethnicities from the strong majorities, and (if they were strong) they could not even employ their own working classes or upwardly mobile.
National Socialism, on the other hand, was a lower-middle class movement of engineers and technocrats. People who had too much education to find jobs in a democratic regime that wasn't producting enough colored flavors of toothpaste and soft drinks to keep its talent employed, simply because the stock market was down. National Socialism on the other hand, said the sky was the limit and anything was possible with German talent. Capital is no longer a pillory serving the financial caste but the tool of the State in manufacturing national culture.
It just so happens that there were other pressing issues, namely the revenge of the Versailles regimes who wished to reassert the status quo of Germany as an economic colony instead of a world power--and thus the result was war with a superior foe which (predictably) won.
So all that German talent was put into rearming for war on a shoestring--and a remarkable shoestring it was. Without the imperative for war to settle Germany's problems (which were very real and none of them created by Hitler) then Germany might have indeed produced a lasting national culture, and by that, world culture, as any addition of culture is worthy of notice. Perhaps a better man than Adolf Hitler could have pulled it off somehow without world war. Who knows? He was neither a God nor a Devil.
In any case, Germany was very advanced by 1930s standards, and this despite rearmament. We never see the good things because they are overshadowed by the bad. There is hardly anyone left who can put things into perspective because the Germans themselves are witnesses to their defeat and have the mentality of a defeated people, particularly those of the postwar generation who can only see greed and disaster because they judge things by modern standards where such cynicism is just business, the way of life.
Now, if I were asked if Nazi Germany was better that the present system today, I would find the question absurd because this is not the 1930s. There is as much water under the bridge now as there was regarding Napoleon's time during the Great War. Any kind of progressive philosophy or movement would have to learn the mistakes of the past and incorporate from a rich set of ideas, borrowing from many historical patterns. I'm not afraid, for example, of looking closely at a Communist idea that had merit, such as a worker-owned factory in Tito's Yugoslavia or something from Nazi Germany.
Stagnation, however, is to be avoided at all costs. Sure, sometimes change is a gamble, but hopefully a calculated one and not for cosmetics or for its own sake. Stagnation benefits only the established classes and squeezes merit and talent into the mold of serfdom when the financial markets are expansive, and into oblivion otherwise. Produce/consumerism turns national culture into the equivalent of an MTV dinner: High in calories but low in nutrition and taste. It is an intellectual wasteland where leadership is pointless and nations are aimless. That is to be avoided, IMHO.
