I would have to say Unearth is moreso on the "metal" side of the "Metalcore" spectrum, I think bands such as All Out War, Full Blown Chaos, Remembering Never, Martyr AD, Acacia Strain, etc., fit more comfortably on the Hardcore end. Metalcore has become the reason I quit going to shows, between teenybopper girls talking about homeroom and Danny's new haircut, and Danny with his new fucking haircut giving hugs to people after his band plays eight songs chock-full of gallops, harmonizing, breakdowns with snare hits on the three, wide-leg guitar stances, and awkward "between song" banter about his 14 year old heartbreak at the age of 20. But I still listen to very few metalcore bands, i.e. Wings of Scarlet, Nehemiah, Skycamefalling...maybe more...
