Simon: And in particular in Magic: The Gathering, where it comes up a lot. Because printing card A strictly better than card B makes card B not much use, and annoys people, but making it better in _almost_ every way is ok.

Also because the dividing line is often interestingly contentious: eg. a creature card is normally strictly worse than the same creature card with the flying ability. However, if the metagame has many people playings card that damage flying creatures but not non-flying creatures, you may sometimes prefer the other card.

I'm not quite sure how to parse "strictly better", but I think it is both clear, accurate and unambiguous (if you assume you can compare each aspect of the things).

I was expecting to be able to apply notions of orderings, specifically that if the object is better in some ways and worse in others, then as a whole they're incomparable (unless you define specific weightings), giving a description like "comparable and better". But that doesn't sound very good, and is likely to be misunderstood, even where people might understand that you meant "incomparable" in that sense.
