I don't know that 72% to 65% is comparable or slightly higher. That seems like a gap to me. And the fact that BMW ranked 10th last year isn't great.

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.

The reliability rankings are determined by surveying people and asking them the frequency of repairs.

Assuming my paper airplane never goes into the shop it’s going to outrank the F-18.

Ain’t a better plane though.

Well, again "better" is subjective and you would want to agree on some metrics before deciding.

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?

Better in this case is durability and there's no way of BMW is more durable than a Toyota Corolla and that is objective.

A brick handily beats both.
