What's the Best Movie to Ever Win Best Picture?

We are in the heat of Oscar season and it has me wondering: What's the best movie to ever win best picture?

I made a list of all the winners, so you don't have to. You can find it here: https://www.peliplat.com/en/list/collection/10071697/academy-award-for-best-picture-winners

When I look at this list, three movies stand out as the best: The Godfather, Rocky, No Country For Old Men.

There are a lot of great ones though.

I wonder, what do you think is the best movie (or top 3) to ever win best picture?
