I dunno, there are some good acts like Killswitch Engage, Trivium, As I Lay Dying, Lamb of God, Underoath, etc. Just my opinion though. I'm more into Converge, Dillinger Escape Plan and Between the Buried and Me for metalcore. HORSE the band is fine too. I prefer post-hardcore though. Mass of the Fermenting Dregs is pure, unrelenting awesome.
