TOS - "Balance of Terror" - always loved that episode.
TNG - Yikes so many to choose from! "Fist full of Datas" for one but one of the episode that sticks in my mind (and surely thats the sign of a good one!) is "Dark Page". Very sad but beautifully done, I have a ship named "USS Kestra" because of this.
DS9 - Without a doubt "way of the warrior". The battle sequence..well...breath taking. The Dominion battles latter in the series just didnt seem to have the Same impact to me.
Voyager - Had quite a few episodes that I liked but the ones I tend to watch over and over are "Pathfinder" and "Blink of an Eye"
Enterprise - hmmm this never really grabbed me. I always got the impression they were groping around for a reason to make episodes! It started to find its way in the last season and, I think, was cut off before it could expand. It had a lot of "Lore" to develop on. I think the episodes I liked were "In the mirror darkly1 & 2".
------- "May the fates hold off the coming of the storm"------
I'll go with sacrifice of angels. still one of the best space battles ive ever seen, a real thrilling episode (the only moment in all of trek where i actually thought 'yep they're screwed), a great conclusion to a 7 part story arc and an emotional end. simply brilliant.
Hard to choose... But if I had to go with just one, it's gotta be DS9's The Trouble with Tribbles. The fact that they actually "Cut" the actors into the TOS scenery along with Kirk, Spock, etc is just awesome.
im not entirely sure i could pick just 1. Best of Both Worlds for TNG, The Way of the Warrior for DS9, Timeless for VOY and I have to agree with the OP on Terra Prime for ENT.
I cant speak for TOS mostly because i can never make it through more than 2 episodes before i fall asleep sadly, but from the ones that i HAVE seen, I would have to say The Menagerie or City on the Edge of Forever
*Me*Why don't you just step away from the weapons console. You and I both know that you couldn't hit that cube, even if it was right in front of us.
*Junior Tactical Officer* But sir the cube IS right in front of us.
*Me* EXACTLY! Its right in front of us and you still missed it! Just step away from the console.
