Favorite Alfred Hitchcock films?

I just recently started watching some of his films for the first time. Being younger I just recently started watching older classics. (Citizen Kane, 12 angry men, Casablanca, etc) Over the past few days I've started my first Hitchcock binge. Watching Vertigo, Rear Window, The birds, and Psycho. Amazing films! Just wondering which Hitchcock films are your favorites.
