I'm sure some aar going to say I need my head examined, but I'm going with "The Infinite Vulcan." The Phylosians looks damned cool and I rather like the story. The only part that's WTF! is the fifty foot clones---why-oh-why did they have to do something so stupid???
When you read the ADF adaptation you can imagine you don't see that. But everything else is pretty good.
"How Sharper Than A Serpent's Tooth" is more-or-less a retelling of "Who Mourns For Adonais?" And can anyone tell me how a winged serpent is supposed to command such high tech when he doesn't have any manipulative limbs? His ship looked kinda nice.
