My personal favorites were not listed.
In no particular order:
Darmok
The Inner Light
Hotel Royale
The Inner Light
Huge fan of these two, with perhaps The Inner Light being one of my top 5
"Darmok" is another widely loved episode within the TMG fan base, but it again did not make the world move for me. Yet it did become an inside joke with the two Star Trek Fan drinking buddies I ran with back in those days.
When one of us was asked how our latest date went, the reply would be:
"Okay, but not as good as the ménage à trois... I had with Darmok and Jalad at Tanagra!"
As to "The Royal", let me just say you won't like my upcoming worst list--
