Okay... this genuinely hurts. I will kill off "Parth Ferengi's Heart Place". Taking out an episode that has DS9 characters feels like I'm personally betraying myself. But the others ARE superior episodes.
And my final vote goes to... "No Small Parts". ONLY because "wej Duj" is one of my favorite episodes of the ENTIRE current era. "No Small Parts" achieved no small feat by making the Pakleds a legitimate, genuine threat... that is some serious skill these writers have. It definitely earned itself the runner up spot for me. (With what was left, at least... I'd likely put "Hear All, Trust Nothing" as the runner up if it made it to the Finals. That was an episode of absolutely pure joy for me.)
