I'm surprised that so many people voted "no single aspect"
Sometimes with selective breeding, a truly spectacular specimen really only exhibits one "single aspect" to such a degree, that I consider it a truely high quality animal. A clown might just be another clown, but the extraordinarily reduced pattern clown stands out, with one single aspect making the difference between "another nice BP" and "extaordinary".
Granted, being awesome in many regards is preferred, but I do think that "single aspect excellence" animals, in many cases, can be defined as "true quality animals"
