I can't decide, there are so many good episodes and films.
I'll save The Search for Spock. A wonderful film for the visuals alone, with Genesis changing so much throughout, right until it falls apart completely. There is also so much going wrong for Kirk in his quest to find and restore Spock.
The Enterprise escaping the Spacedock is one of my favourite scenes in the film series as well.
