Cardioid response simply allows you to hear more direct sound, the Kiis and 8Cs can be placed close to the wall to increase headroom, ensuring no self cancellation and because their bass output is adjustable. The only way to adjust passive speakers traditionally was to shuffle them backwards and forwards until you find the quarter wave distance of the frequency which is causing the boomy bass.
@Matt yes they are better than any passive speaker in every possible metric.
Just to add you can’t really compare two loudspeakers unless you have them side by side in your own room, which I have been fortunate enough to experience.
