It's a silly question for a cinephile. There are numerous great directors masters of their art who have all contributed the fabric of cinema. Placing one above the other is a pointless exercise.
You have omitted so many directors too. The Russian school ? Tarkovsky, Konchalovksky, Zvyagintsev, Vertov, to name just three. Or even directors like Klushantsev inspired by Cosmism that in turn inspired Star Wars. The Czech school especially the New Wave. Forman, Juraj Herz, Vera Chytilova to name three. The Polish school Kryztof Kieslowski, Andrezj Wajda, Polanski to name but three. The Hungarian Bela Tarr. The numerous French directors like Claude Chabrol, Eric Rohmer. Germany from Lang onwards to Fassbinder & Wenders. In Britain from Pressburger to Loach & India with Satajit Ray.
There is a huge world of cinema out there with so many superb films most people who utter Spielberg (who is a very decent director with the likes of the masterpiece that is Schindler's List) don't even know about. Not even forgetting Italian cinema & Italian horror & realism too.
