The quality of Coca Cola can only be compared to other colas. Comparing a soft drink to an imperial stout makes no sense. In my book, the imperial stout always has zero quality, because I would never see a reason to voluntarily drink it, whereas I might indulge in a diet coke every now and then.

But that’s why comparing subjective qualities of different things is a waste of time.
