I'll give it a shot for TOS.
Top 10, plus bonuses:
- Space Seed. Great episode, plus backstory for The Wrath of Khan, which is my favorite ST movie by far.
- The Trouble With Tribbles. But they're cute!
- Mirror, Mirror. The original mirror universe ep. Bonus: The Enemy Within.
- Amok Time. Spock, amok.
- Arena. Gorn wrasslin'!
- Balance of Terror. Those Romulan dastards. Bonus: The Enterprise Incident.
- The Doomsday Machine. Great ep.
- The City on the Edge of Forever. Best overall ep?
- The Devil in the Dark. Personal favorite.
- The Naked Time. Great ep, much Spockage.
