Well, I like "Zuckerzeit" a lot and have just listened to it again with regard to what you said about polymetricity. Yeah, that second to last one that Moebius wrote is really schizoid and irregular. Nonetheless, though, I also think that the best Dieter contribution on that album is "Rote Riki" which is just 2/4 and all the more hard-hitting because of it.
