No, it's more like comparing a diamond with gold. They both have their own particular qualities and according to taste you may have a preference for one but neither is better in any meaningful way as taste is subjective. I love Michael Nyman and love how he can arrange and compose music, but that doesn't mean I have less regard for Lou Reed who claimed to have mastered only a few chords. Michael Nyman would struggle to find the words and intonation that came so easily to Reed, but Reed wouldn't have the patience to do what Nyman did. They are just different types of music and both excelled in their fields. London Calling is a sublime album and I don't think it is like comparing a 9th grader with DaVinci at all. It's more like comparing Van Gogh with Da Vinci. They are very different artists and maybe you prefer one over the other, but Van Gogh was every bit as valid. London Calling is up there with any album. Mind you, you would have a hard time finding an album as bad as Cut the Crap, but every band or artist loses their way at some point. Maybe they have retreated back into the 9th grade when it comes to the career low point, but at it's peak, it is sublime and up there with anything else. It has the passion, energy and soul and that's what music should be. Pink Floyd are a very technical band, but I find them so fricking boring. That's what happens when middle class architects form bands.
