This is exceedingly difficult. I can't bear to give it to "IN A MIRROR, DARKLY"... the awesome title music and sequence used alone made it great, never mind how much fun the episode was and a clever explanation of the origins of the Terran Empire we know. (You have no idea how much the regular theme song annoyed me.) And the episode, in a roundabout way, cements the ideals of the Federation and STAR TREK... that we are all better and achieve greater together. Think about it... the Defiant was sent back in time over 100 years. That means the Empire was basically stagnant in technology for a century because when we see the mirror Enterprise, she has almost the exact same technology.
And as much as I love the suspense and great character work of "MINEFIELD", "AZATI PRIME" was more memorable and a big game changer. My point, reluctantly, goes to "MINEFIELD".
Minefield - 2
Azati Prime - 0
In a Mirror, Darkly I - 0
