I think he's asking "big picture", who cares?

I'll say that there's a big difference between cereals and jell-os than there is different types of snack cakes, so maybe mentally they're just catalogued differently in people's minds. The short prints also differ between the two sets, plus there were only three years of them, so they're easier to keep straight. And they've got the 1950s/60s superstars, rather than the less interesting 1970s stars.

And even being 10 years earlier, the supply is less making them a more satisfying chase.
