Sometimes boldly going involves sitting at benches, banging gavels, and giving a good speech or three—but we’re entering our own tribunal to sort the best from the rest.
Personally I would probably put "Devil's Due" at number one, but I realized not everyone can have such a refined taste in Trek.
That's my feeling on it. They all have something to offer, and for the most part did a good job telling a story. It's like comparing two nice bottles of scotch. Which is "best" depends on exactly what you're looking at , and your mood. It's also largely subjective. Pick one, and appreciate it for what it is.
This is a really good and very Star Trek point, and thank you for pointing it out. It reminds me of Naomi Wildman telling Seven, "cooperation is more important than competition".
