In rough descending order:
1. Count Dracula: This BBC production is the best, most faithful version. Moody and atmospheric despite a low budget. Fantastic performance by Louis Jordan as the Count. Watching this on Halloween on PBS was a ritual of mine as a child.
2 (tie). Nosferatu: Both the silent original and the Herzog remake. Probably the weirdest, creepiest versions of the story. The "ship of doom" sequence in the original and the "feast with rats" scene in the remake are particularly memorable.
3. Dracula (1979): Takes a few liberties with the story, but Frank Langella is great as Dracula and the feel of the film is suitably dark and gothic.
4. Horror of Dracula: Takes way too many liberties with the Stoker novel, but must be mentioned due to the presence of Christopher Lee as Dracula and Peter Cushing as the best Van Helsing ever on screen. Greatest climax of any Dracula film.
5. Bram Stoker's Dracula: Really Francis Ford Coppola's Dracula. I've got a love/hate relationship with this one. It is gorgeously filmed, and is probably the most faithful big screen version of the story. There are some great scenes. Yet some of the performances are a bit much, and the whole thing teeters on the edge of total camp.
