Pareto superior seems about right.

So it does, after a quick check with the Big W. Shame it isn't widely understood enough for my needs, though; I for one would have had to look it up if anyone had used it to me!

Use it, explain it as necessary?

If people want concise terminology, they have to learn it. If they only want to use simple terms, they're going to have to put up with more verbose chains of them to explain anything accurately.

And between that and "in the product order" you've covered _several_ classes of people :)
