Unless you think the word quality is just fully synonymous with reliability (in which case a paper airplane beats an F-18) then my point stands.
Quality is famously subjective, that's why you'll never see it ranked in a way that everyone can agree on the way you can with reliability which is actually measurable.
But reliability is one of the markers that most people would use to judge quality. And we generally expect aircraft to go where we want them to without catastrophic failure, so I would think that an F18 is more reliable than a paper plane.
Assuming my paper airplane never goes into the shop it’s going to outrank the F-18.
Ain’t a better plane though.
Say I wanted a low-cost, lightweight, hand-propelled aircraft capable of flying short distances indoors that I could fold up and put in my pocket afterwards? Which would be the "better" plane then?
And Toyota consistently ranks higher.
