Both directors were awesome but there newer movies are pretty bad. Ridley's classics: Alien, Black Hawk Down, Gladiator Recent: Prometheus, Gods and Kings, Robin Hood Mann's classics: Heat, Collateral, Last Of The Mohicans Recent: Miami Vice, Black Hat, Public Enemy I'd have to go with Mann. He fell in love with using hand held cams and the acting has gotten worse. You'd think Foxx can't act based on Miami Vice. His lighting is pretty bad too since he relies on "natural lighting." Scott has made some boring movies like Robin Hood but they're still more entertaining than Mann's. Prometheus was a disappointment but still had cool scenes, similar with Gods and Kings.
