DS9's action quota was way below DIS. But don't be fooled: The war was what kept DS9 alive. It was always there, lurking in the background, and everyone everytime having to deal with it's consequences. Even Vic Fontaine was mostly there for "contrast" his lush style with the grim "reality" of this series. Don't get me wrong, it worked great. But in retrospect, "war "clearly was at centerstage through all the watchable episodes of DS9, and many many of the filler plot-of-the-weeks.
How was war involved with the suburb dramas like The Visitor, Far Beyond The Stars, or Hard Time? Or lighthearted comedy episodes like Little Green Men, Trials & Tribble-ations, or Our Man Bashir? Hell, the early episodes dealing with the Bajoran occupation, like Duet and Necessary Evil, weren't really war episodes per se.
I don't think the Dominion War episodes actually have a history of hitting their target much more frequently than the non-Dominion War ones. There were maybe a half dozen which were superb (mostly standalones or two-parters) and a lot of good to okay ones.
