Pinochet, after the chaos helped bring a peace to chile with a new Liberal economic model that fixed the mistakes of Allende.
He achieved his goals, greatly impoving chile and was never persecuted for a single crime. He won.
Allende greatly improved the living standards of the working class. He was overthrown by the CIA for going against the US companies that controlled 80% of Chile's copper
Meds there was massive inflation and a huge lack in food.
Under Pinochet the nation experienced a economic miracle which paved a way for Chile's future even after he left.
That is of course not to say that his reign was all good, it was still a dictatorship for the vast majority of his rule and thus resulted in the violation of human rights aplenty. But alas his achievements in improving Chile could not be underestimated.
