>vastly superior weapons
Not even close. They often had objectively worse weapons and also often lacked supplies and food.
>fighting men
They were about on par with the British and Americans. They were better 1:1 against the French and Russians, sure.
>leaders
They literally had a suicidal delusional idiot as the leader. Good leaders like Guderian and Rommel were just overruled by him.
