looking for a list of metals most corrosive to least
I agree with almost everything you said except that I prefer American metal because I'm more into thrash (Testament, Metallica, etc.) and stuff like Ozzy and Black Label Society. BUT I also like European metal. Iron Maiden, Judas Priest, and Celtic Frost rule.
there's so much diversity in the metal genre, especially with the underground metal scenes, that it's really inaccurate to lump it into just the two groups american metal and european metal. Many american metal bands were influenced by european bands, and vice versa. Both areas of the world have their fair share of awesome bands, and crappy ones too.
European Metal definitely. I like plenty of American Metal bands, mostly American Thrash Metal bands and the Death Metal scene, but Europe has a lot more quality bands and a bigger variety of sub-genres. Not to mention less mallcore metal bands and less nu metal as you already mentioned.
That's pretty much no contest. European metal. Scar Symmetry, Solution .45, Dan Swano, Edge of Sanity, Cyclamen, Iron Maiden, Firewind (originally Greek), Behemoth, Bloodbath, I could go on for aeons.
