Just looking at the past 15 years [1998 to present, which would include Nolan's entire filmography], you get:
Nolan: Following, Memento, Insomnia, Batman Begins, The Prestige, The Dark Knight, Inception, The Dark Knight Rises [8 movies]
Spielberg: Saving Private Ryan, AI: Artificial Intelligence, Minority Report, Catch Me If You Can, The Terminal, War of the Worlds, Munic, Indian Jones and the Kingdom of the Crystal Skull, The Adventures of TinTin, War Horse, Lincoln [11 movies]
Yeah, I'd take Nolan over the past 15 years in a heartbeat, even though I did enjoy most of Spielberg's movies during that same time frame.
