> But I disagree that it's extra sweet and fatty. To me, Miracle Whip, which is what my family used as and called mayonnaise, is much sweeter.

True. And grosser.

I checked the ads for one of those once. As Monkeyman suspected, it's definitely only 6 grams of fat or less if you don't put any mayo on at all.
