Together, DS9 and Babylon 5 are rightfully credited with innovating the long form series. What the kids today might call "binge worthy."

Their story arcs were known from the outset. Each (main) character has their own hero's journey and side quests. Both had satisfying endings.

Also, officially, Capt Sisko is the GOAT. With Capt Janeway placing a strong 2nd. Though Capt Pike (Strange New Worlds) is quite promising, but only time will tell.

Whereas Voyager has most of my most favorite episodes, esp wrt Ensign Kim, DS9's characters are legend, esp Quark. I couldn't pick a favorite DS9 character (or story), even on pain of death, because I cherish them all equally.
