The winner is arguably Monty's best-known story, while the runners-up are both full-on horror tales and much anthologised. So a bit of a split vote, I suspect. My big mistake in this poll was trying to limit the field to just ten stories instead of listing them all, then weeding out five or six that couldn't win. One lives and learns.
Surprises? 'The Mezzotint' pipping 'The Ash-tree', and a strong showing for 'An Episode of Cathedral History'.
