I’m going to say George Lucas. Unironically. I like the Theatrical Cut of American Graffiti, THX 1138 and Star Wars. Before he made changes to the films in the 1990s and 2000s. I also don’t hold the belief that just because he made the prequels he never was a good filmmaker to begin with.
My second favorite Is Steven Spielberg because of Raiders of the Lost Ark, Close Encounters, Jaws and ET.
Third favorite is Francis Coppola for Godfather 2, The Conversation and Apocalypse now.
Fourth is Richard Donner for Superman 78 and Goonies and Lethal Weapon.
