It might be better and have a lower kill count, but you're wrong on many points.

Communism revolves around ending private property ownership. National Socialism does not. This is such a major difference between ideologies that it alone disproves your claim.

It is still fundamentally a form of socialism and it comes right up the the line on private ownership. It's still your factory, in theory, but here's a party member to dictate how 90% of it gets run, and who you can employ. It's partially yours, on paper. Better? Sure, but not by that much.

Communism is based on egalitarianism DEI bullshit. Equity is it's only goal. National Socialism was based on natural hierarchies selecting the best of themselves. Quality was their aim.

No, it sought to eliminate class hierarchies (it is, after all, a socialism) and it wasn't exactly trad in regards to sex and the workplace (sex is more complex, because they also highly promoted and paid for motherhood due to their other concerns). It's not all hierarchies, sure, but it is not as free of proto DEI stuff as you might think.

National Socialism only required ONE nation to act in it's own interests, together.

A significant part of the nazi belief was a socialist and sort of Malthusian understanding of the world's economics. They needed lebensraum. Not for any particular resource, or just space for hypothetical larger future generations, but because their economic theories said the world and economy was doomed and they needed more if the German people were to not starve.

It was all for the benefit of one nation yes, but it needed the space of all others.
