I’ve always loved the episode “Disaster” from TNG. I just like disaster shows and this one has all of the cliches and is well acted and tugs you out of the safe little box much of TNG is in. Recounting from memory, the Enterprise runs into these almost undetectable bubbles in space that renders the ship immobile and drained of its energy. Different crewmembers are trapped in different areas of the ship and must find a way to survive until they can pilot the ship out of the bubble minefield. Picard gets trapped with a bunch of kids on a turbolift, Dr. Crusher and Geordi get trapped inside a cargo bay with a plasma fire, Worf is in Ten Forward with a lot of random people and a pregnant Keiko, and Riker and Data were in a Jefferies tube I think. I like the episode because there are a lot of interactions between crew members that normally do not have a lot of screentime near each other so this gives them a chance to develop some chemistry.
With all due respect, the best line of the entire series is “So, Commander, tell me about your genitals.”
Almost forgot the best Ferengi episodes on DS9.
Quark - The House of Quark is the one where he marries a Klingon woman and has to face down a Klingon challenger. It was the first time we see Quark as a dignified and admirable character.
Nog – It’s Only a Paper Moon His best episode is when he recovers from losing a leg in battle. He’s a shell shocked vet that finds comfort at Vics nightclub. One of the Best Ds9 episodes.
Rom - the one where he organizes a labor strike against his brother.
For a laugh watch the Janeway episode where she starts falling in love with an Irish hollodeck character.
Paris writes a nifty hollodeck program with an authentic Irish village. Janeway falls hard for this handsome fellow. Before things get too kinky she shuts down the program. 
Hollodeck sex was only hinted at in Voyager. In DS9 Quark ran a Hollodeck brothel. But, it was never, ever shown. They did have a kinky episode where a client wanted Kira. He paid Quark to get her DNA to make a hollodeck copy of her.
What, no Darmok?
And what may be Worf’s second-greatest line of all time:
“Congratulations. You are fully dilated. You may now give birth.”
I enjoyed watching In a Mirror, Darkly. It was a pair of Mirror Universe episodes, so it doesn’t really count as Enterprise, does it?
Just realised no one has mentioned “the defector” yet, which I think is my all time favourite TNG
In Body and Soul, Tuvok gets his pon farr on and Paris relieves his stress by creating a holodeck simulation of his wife for the express purpose of hot kinky holosecks.
I almost think this board could support a Star Trek subforum.
I finished running through all 7 seasons of TNG last night. I started in February with Netflix. I start season 3 of DS9 this week. I never watched it when it originally aired, so it’s all new to me.
DS9 is so awesome, and season 3 is where it really starts to take off. Next year you get Worf, who shows up amidst one of the greatest season openers ever on television (The Way of the Warrior).
As does Vorik in “Blood Fever.” I always wondered what the rules were for holodeck shenanigans - I mean, once the holograms disappear…well, watch your step, everybody!
The holodeck converts energy to matter and vice versa. If it can create a tommy gun with real bullets (First Contact) and weapons that can can kill (Worf’s holodeck workout), it can remove holosex spooge…
Actually, it doesn’t convert anything to matter. If that were the case, you could carry objects out of the holodeck, which you cannot do (excepting production goofs, of course).
One of the great mysteries of treknology is what the nature of holodeck-created food is. It’s been speculated that all food items are replicated whereas most everything else is simulated with force fields.
It was on our office top ten TNG, along with “Inner Light” and “Tapestry”. Also, it was in the OP 
“Q Who” was a pretty good episode of TNG. Q, being Q, the Borg, being Borg. Given that it was relatively early on in the show’s run, the writers haven’t yet ruined those two protagonists. I’m not sure if that’s covered by the OP’s “center Q” episodes.
I can’t remember what else we had on our list, it seemed pretty Picard and Data heavy. “The Measure of a Man” was decent enough, but I’m not sure how a casual viewer might take to it, “Brothers” was more enjoyable perhaps.
So was the acting talent.
Oh burn!
TNG never really seemed to make the episodes where other cast members took the spotlight seem as bad as Voyager did. Maybe the acting talent amongst the lower caste of TNG was a bit better than that of Voyager’s bottom rung.
The extras on TNG were better than Voyager’s leads could ever dream of being.
From TNG:
A lot of my favorite ones have been mentioned.
I was especially pleased to see The Inner Light get top billing - it’s one of my favorites.
Here are a few other good episodes:
11001001
Tin Man
The Arsenal of Freedom
Remember Me.
I take exception to that. Tim Russ, Robert Picardo, Robert Duncan McNeil and Kate Mulgrew were excellent on Voyager, because they were usually given good stuff to do. Just watch how Captain Janeway manages to somehow stretch the word “now” out to four syllables whenever she’s angry, and manages to do it sexilly.
Robert Beltran was lame mostly because his character was bland as hell and had no definition. Kes, Seven and Torres were rarely given anything interesting to do, Harry Kim was a whiny boob, and Neelix was just fucking annoying.
All the actors on the show are accomplished performers, though. (Check out Beltran’s character on the last season of Big Love, for example.) But nobody ever bothered to write anything competent for their characters.
Voyager was such a huge disappointment.
