One of the reasons they specifically lost the war was because Hitler was such a fuck up that he was decimating the German economy. When you look at how the war was progressing, the only outcome for the Nazis at the time was either defeat or collapse. Combined with the endemic usage of Pervitin and other drugs at this time both to fuel soldiers and keep the citizens relatively placated they were burning up everything both at the frontline and at home.

Bingo: the story of WW2 is that the Germans started with an effective army, and the Nazis ran it into the ground.

The saddest thing is subsequent decades of bizarre interpretations of this result because people got too excited about some effective German industry that they took Hitlers various wonder weapon attempts as planned engineering projects rather than engineers trying to put form to a mad man's rantings.

Hitler loved the idea of super heavy tanks, so the Germans kept trying to build them even though they were unreliable, ineffective and vulnerable.

Meanwhile the Sherman got a reputation for breaking down a lot...mostly because it kept surviving and being fixed in the field and continuing to provide effective armor support, whereas German tanks just died.
