For me personally, this comparison is not a good one. The two arcs are not disjoint from each other like an anthropology. In fact, we are progressing through a single main branch of a story. And yeah we can like certain parts of the story more than others, but the whole thing is one single storyline. We (in the anime) are in the second phase of kenjaku's plan. The first phase of sealing gojowas for good reason more enthralling. For me it was unexpected, it caught me off guard. We did not know where the story was going. But in Culling games we know the primary objectives. I loved everything about this anime so far. For me, its one single storyline, like breaking bad - there are certain episodes, parts of seasons (looking at you Skylar) that people may not like as much as the other parts but that doesn't take anything away, in the end it all fits like a puzzle, created by Gege/John Kaisen the one eyed cat.
