So, who is the best, and why?

Metalheads have more pull in opinions, because they listen to this stuff more. I think I know who are the metal heads on saints report, so let's hear it.

I wouldn't classify all these bands as "metal". Some are just "hard rock". And just when you think you have it sorted out, someone comes along to blur the lines, which is how subgenres get created. And the subgenres of each class are almost too much to keep track of. And the names of some of these subgenres....hair metal, glam metal, speed metal, thrash metal, doom metal....are misnomers; as they aren't really "metal", but subgenres of "hard rock". These subgenres tend to describe a bands appearance, moreso than their musical stylings, IMO.

In very broad and general terms, at its basic premise, blues is the basis for hard rock, while classical music is the basis for metal. Generally speaking, hard rock tends to be lighter in nature/content, happier, optimistic...a "celebration" of something; while metal tends to be darker in nature/content, discontented, and somewhat pessimistic. Hard rock tends to be about a "self" experience, while metal tends to be about a larger societal experience or issue. As a result, hard rock musicians place a higher priority on partying and getting laid; while metal musicians place a higher priority on musical talent and instrumental proficiency.

We're painting in very broad strokes here, and there are exceptions to every rule. If the above criteria were a checklist, we're looking for the "overall fit", as very few bands are going to fit 100% entirely within a classification. And it is somewhat objective, subject to individual interpretation. But in my opinion, many of the bands on that list are "hard rock" bands, not metal bands. Here are my outlooks on each listed band:

Of course, these are all just my opinion. Subject to interpretation by others, as well!
