Yahari Ore no Seishun Love Comedy wa Machigatteiru. Zoku

Both series are similar in the regard that they focus on an emotionally exhaustive love triangle. They also the struggles of changing the status quo of a friendship. Oregairu Zoku is much more subtle in presenting its topic than WA2, but if you like one of them, you will enjoy the other.

3-gatsu no Lion

I can't help but to think about Shigatsu wa Kimi no Uso when watching 3-gatsu no Lion. Similar titles aside, both feature the same premise; a prodigy young man's struggles to cope with the depression of losing a loved one. Both series feature a prodigy MC (Rei and Kousei) who are similar in looks and personalities and female figures (Kaori and the Kawamoto siblings) who came inside the MC's life and help them overcome their depression. The MCs also gains many rivals and friends throughout their journey in their career. Even though I found 3-gatsu's tone more consistent and its comedy less forced than Shigatsu, I enjoyed both works and guarantee if you enjoy one of them you'll enjoy the other due to their similarities.

While Oyasumi Punpun is more of a coming-of-age story and Not Simple is more about the tragic tale about a young man, they are equally dark and both series' main characters have a pretty dark and troubled life.

Tokyo Ghoul
|
An ordinary high-school/college student gets turned into a monster by an unfortunate accident; this pretty much mirrors the main plot of these two seinen mangas. Both also deal with how the main characters struggle to preserve their slowly declining senses of humanity as more things happen due to their new nature. While I enjoyed Tokyo Ghoul more, both mangas are nice reads.

While Psycho-Pass revolves more around chasing a criminal and Rainbow is more about the life and friendship of seven prisoners, both series center around laws and have criminals as their main theme, and explores both themes pretty nicely.

Both revolve around high-school students' activities in their respective clubs-- the Literature Club for Hyouka and the Service Club in Oregairu. The male protagonists of both shows are generally cynical and lazy, yet intelligent people who joins the respective clubs to get more involved with people. The main difference between these two series is that the characters in Hyouka solve mysteries, while Oregairu's solve daily life problems.
