A popular response to the scenario"Band Y is far more talented than Band Z" is often, "that's only your OPINION"
So the question than becomes this: Can Band Y be objectively better than Band Z?" Or is it really only a matter of subjective judgment? In other words, can a certain band or artist be objectively better than anther band or artist?
When I say that Alice in Chains is a far more talented band than Nickleback, is this objectively true, or is it just a matter of my opinion? How about saying that Jimi Hendrix was a far greater musician/artist than Justin Bieber is?
What's your take on this? Is Radiohead REALLY about a trillion times better than Limp Bizkit? Or is that only my opinion?
