Paul Thomas Anderson. By far. Theres just such dimension to his films, and the use of music, and codes in his movies are amazing. If you take that one scene from Boogie Nights, the first real party scene where Dirk Diggler is introduced to everyone, you will find Eric Burdon and the Animals - Spill the Wine playing in the background and at the same time you are looking at a steady cam shot (I think thats what you call it, where the camera follows the character from behind everywhere he goes), that is great use of codes in movies, you dont see that in Wes Anderson's films. As well as the plots are more interrelated and more developed, complexed in PTA's films.
