Harmony of Despair wins for me, in a point of view of diversity. Judgment has too many "classics" we heard remixes 150.000 times, while HoD offers pieces I'd never expect to be remixes (ex: Festival of Servants, Poetic Death, Invitation of a Crazed Moon, Piercing Silence, etc.).
Plus I prefer the rock approach they took with HoD, though Judgment's arrangements give us more new things than HoD's.
