I tend to concur, overall it was the best of the group so far. Although I have to agree that Sisko did go "ABM" a lot......with Eddington, e.g., and in the reality-warp back to the Golden Age of Sci-Fi, when the ensemble appeared without their latex, and we got to see what Marc Alaimo and Armin Shimerman looked like without all the Michael Westmore physiognomic magic. That whole episode was full of grace touches -- I even liked the hat-tip to the screenwriters: "Commander Sisko sat at his desk and looked out the window...." Plus, the final episode was just great -- and everyone went to the wrap party in costume, which was filmed and rolled into the story line. I kept that one.
But the best episode of them all, bar none (IMHO) is from TNG: it's the time-loop conundrum, in which Kelsey Grammer guests in a cameo.
The Best of Both Worlds: Parts 1 & 2 were the best episodes ever to come from Star Trek. ;^)
