That's sort of a loaded question, given how much our society has changed in recent times. Twenty years ago, I would have said that Gingrich represented "American family values" better, given, if nothing else, some of the stranger things that Giuliani has done. Today, I still think that Gingrich better represents what Americans would like to think of as traditional family values, although not nearly so many Americans are actually living by those standards anymore. Still, people tend to expect more of their leaders than they do of themselves (they like to think that their leaders are better people, overall), and in spite of his affair, Gingrich still adheres more closely to what Americans have traditionally expected of their leaders than Giuliani. Personally, I don't care for either one of them. Giuliani strikes me as an embryonic fascist, while Gingrich wants to invade and occupy half the Middle East and North Korea.
