Let's not go too far in the other direction glazing Mao. Dude was a great military leader and legendary political revolutionary which is a lot. But he didn't have incredible precognitive psychic powers like the God-Emperor, couldn't turn an devastated illiterate starving agrarian country into an sophisticated wealthy liberal European wakanda over lunch and he wasn't immune to the Peter Principle. He fucked up, because that's what happens when you try to do things. Nation building is an iterative process that takes generations. Mao demolished the old house, laid the new foundations which the new house is built upon.
70/30 is reasonable.
