The missions in both books generally work best in Classic style. In Alpha Complex Nights, "Sweep of Unhistory," also works well in Straight, and "Spin Control" would probably work well enough in Zap style if you can get your players to focus long enough on the plot.
In Sector Zero, "The Dinner Party" works just as well in Straight style as in Classic.
In these kinds of discussions, it's always useful to remind PARANOIA Gamemasters that the three published play styles are only guidelines, and that every GM inevitably picks and chooses from a variety of elements to create his own unique play style.
