More memorable and meaningful than puffery.
Headlines and sig lines (or strap lines) can be the most memorable part of ads. But all too often they're meaningless fluff.

"This bread is very nutritious." or "Builds strong bodies 12 ways." No contest which would be remembered.

"This fine automobile is really quiet." or "At 60 miles an hour the loudest noise in the new Rolls Royce comes from the electric clock," the 1958 Ogilvy classic.
How about: "We condense a lot of tomatoes to make out tomato paste," or "Who put eight, great tomatoes in that little bitty can?" Stan Freberg's wonderful radio jingle. The ending was a thing of beauty: "You know who. You know who. You know who, In case you don't, it was Contadina."
