So I'm watching an interview that the DS9 cast did recently and it's great to hear the cast's thoughts about doing the show. Deep Space 9 and Voyager were great tv shows but I think DS9 was way more of an achievement for a star trek show. The Dominion war arch was just fantastic and all of the characters were all on point for the entire series. The only casting decision I dislike was swapping from Jadzia to Ezri. I liked Ezri and she was a great character when she got going (which she didn't have alot of time to do so), but Jadzia was a much more interesting character.
