For me, the short story makes it easier to identify the climax of the story, perhaps because I am required to use my imagination more when reading it. Poe creates the damp and cold, the echoed sounds off underground walls, the moisture, the bones, and the ringing of the bells on Fortunato's cap.
In Vincent Price's version, I feel the end comes too abruptly and there is no falling action. The horror of Montresor's intention and actions comes suddenly to the viewer, whereas in the story, it drags on, and Montresor seems that much more evil.
In the version I watched with Vincent Price (whom I love), I thought important details (like the motto on his coat of arms) added to the foreshadowing and ultimate betrayal of the befuddled and unsuspecting Fortunato.
Having to choose, the written version of the story has much more impact in general, and the climax is more easily discerned in the written story than in the video.
