This has been discussed to death, but I'll just add that in my opinion this is like saying one painting is worse than another painting because of the technique of the painter. Never mind that one was sold for $10 million and the other for $100. Sure you can rate something on technique but outside academia hardly anyone does. It is not like most people buy albums based off how good technique the musicians have and after all the better entertainer is the one who entertains the best.

I have also walked the halls of geeky academia where people wrinkle their noses and call these musicians average (at best) while they themselves have wet dreams of being half as celebrated. I think for many it is jealousy. They would more often than not rate musicians on a scale from Great to Bad that is completely aligned with Great Technique to Bad Technique and funnily also completely reversed from Unsuccessful to Successful.
