The Neutral Zone- The Romulans brought back as major antagonist and a pre DS9 Marc Alaimo.
Heart of Glory- We get the first real info about Worf's past.
Elementary, Dear Data- Interesting philosophical debate in what qualifies as "sentient life". Daniel Davis is so good they bring him back later for round two.
Measure of a Man- More debate on the rights of "sentient life", but this time it involves Data.
Q Who?- Cop out choice maybe, but John de Lancie turns in a great performance.
The Defector-Great performances all around and one hell of an ending.
Yesterday's Enterprise-Probably the darkest episode in the series, but fascinating to see it play out.
Best of Both Worlds- One of Trek's greatest cliff hangers and perhaps the high point of their threat to the Alpha Quadrant.
Best of Both Worlds- Not as dark as Yesterday's Enterprise, but damn close.
Remember Me- Dr. Crusher got so few good episodes and this is one of her best.
Devil's Due- An intriguing premise made this one a fun watch.
Redemption- The best Worf centered story of the show until DS9.
Redemption- More Worf goodness. He's come a long way since season one.
I, Borg- Some people complain about the declawing of the Borg that starts with this episode, but this is executed pretty well to be honest.
True Q-John de Lancie again brings the acting chops and we learn more about Q culture...such as it is.
Chain of Command- An obvious choice. Lots of great acting in both episodes of this two parter. David Warner gives us yet another great performance and his scenes with Stewart are superb.
Ship in a Bottle- More "what is reality?" stream of consciousness stuff. Daniel Davis is again excellent.
Lower Decks- A great tale told from a different perspective.
All Good Things-Perhaps not the most exciting series ender, but having it all come back to the beginning definitely makes poetic sense.
I will give you Measure of a Man. Some of the ones on your list I don't remember at all, possibly because the titles are so boring.
I did like the episode with Ardra -- I think it was called Devil's Due. A romp rather than high drama, but I give it props for showing the Clarkean possibilities for Federation tech -- and that Picard isn't fooled.
My nomination for an actually brilliant ep was the one where, by a series of accidents, a village of people on a primitive planet think Picard is a god. His attempts to fix this violation of the Prime Dorective are indeed high drama: "Picard must make a decision" rather than merely "Picard must solve a problem." But like I said, I can't remember the title.
(And I do agree, DS9 was better than TNG in just about every way.)
