A lot of my favourites are more comedic episodes. I think DS9 does a lighter tone type of episode really well. I like "You Are Cordially Invited..."
, "His Way"
, and "Take Me Out to the Holosuite"
much more than "In The Pale Moonlight"
. Along with "To the Death"
and "Trials and Tribble-ations"
, they comprise my top 5.
I love "Trials and Tribble-ations"
most - it's just pure joy to watch from start to finish, with the delightful dialog and wonderful performances. Jadzia's enthusiasm throughout that episode is what made me a huge fan of that character in the first place. Also, the running gag with Bashir and O'Brien is hilarious, and Sisko's 'interaction' with Kirk was priceless.
