what a random and pointless comparison.
One's weekly, the other's monthly. No shit it has way more chapters.
One of the best selling manga ever vs. a niche (essentially softcore hentai) ecchi harem. Again, no shit one has more seasons than the other.
Quality is largely subjective, so whatever, but even then, these are two very VERY different types of stories, so I'm not even sure what the point is. Tsugumomo's also an ecchi harem series, so I'm not sure how the hell anyone thinks he's ever gonna fuck until the very end.
