I did play Overlord H but I dropped it midway because it felt a bit empty. I mean apart from the story missions there was hardly any interactions with anyone else and there was no idle chatter or things that would otherwise distract you while you're going for the main quest.
I think if you expand on that similar to a normal rpg adventure game, Overlod H+ might actually turn out to be pretty decent as compared to the original.
Now I haven't play LoH as I'm waiting for the 1.0 but I'll cast my vote after playing the full release. Tbh, I'm more invested in Danmachi's story than I am in Overlord's. I dropped the Overlord LN sometime ago but I'm up to date on Danmachi (Eng version at least), so my vote might be biased
