What you have to remember is that not only is this a subjective debate, but the KIND of subjectivity comes into play.
Lateralus by Tool, for example, meant a LOT to a LOT of people. To me, it's not just an amazing, otherworldly album. It's one of the very few albums that actually influenced the way I live, and look at things. Fortunately, I can separate that, but others sometimes cannot, and anything less will seem...well...lesser.
The common consensus among older Tool fans is that Aenima was their magnum opus and Lateralus was a step down. I don't see that, at all. I think the leap from Aenima to Lateralus was a bigger leap than Lateralus to 10,000 Days, of course. I think there are some moments as creative as any they've done, but like anything, exposure means becoming accustomed, usually.
I actually think System of a Down's last album was their best. I think Zeitgeist by The Smashing Pumpkins is one of the best rock albums ever. It just depends on so many things.
