I have been made to regret having said this.
What gets me, though, is that is just IMHO, a forum on the Straight Dope Message Board, on the freakin’ Internet. It’s not a professional, scientific poll in a respected journal. It’s not a fucking graduate seminar. It’s not even the SDMB Great Debates. 
Can not people (especially a certain someone) see it was meant to spur on light-hearted, but hopefully interesting conversation? For Og’s sake, one of the options is “Mmmmm…free goo…”! (Thank you, Homer Simpson.) Does that connote dour seriousness?
Anyway, I did indeed try this out as a conversation-starter on some friends and colleagues in real life, with success, in that it did indeed lead in interesting directions, both in terms of seeing whether people thought about the terms in a generic or abstract sense, or whether they needed to imagine a context. None of my friends or colleagues, strangely enough, were moved to apoplexy by the lack of context. So yes, I was curious as to what conversations it might lead to here. Obviously, I miscalculated the level of pretension and elitism favored by certain posters.
Be that as it may, I have found the answers here interesting, also that an overwhelmingly majority of respondents have thus far favored “quality” over the other elements.
I have found it interesting also to see whether I myself think of these elements in abstract terms. I do indeed. And I prefer to to prioritize “quality” as a generality, and most of the time in specific contexts as well.
Thus for me, the topic is not meaningless without context. But even if it is so for others, I would argue that the pursuit of meaninglessness can be a most enjoyable past time.
YMMV.
