Kanojo mo Kanojo Season 2

Both anime's MC dating with various girlfriends, and has similar sense of humor. 

Both shows have a similar plot and the main character has multiple love interests. The comedy is similar and the girl's seem quite alike too.  

Both shows have a guy, who is interested in many girls. The stories are very different though, since in Kanojo mo Kanojo the guy gets a bunch of girlfriends but in 5-toubun he is only interested in finding "the one" from the girls. Nevertheless, the girl characters' personalities match.  

Both shows have the exact same type of characters.- Nice main character- Loud, physically abusive tsundere- The calm, nice one - The yandere- The side character who knows the tsundere in some way and is the last one to become interestedBoth shows have a strong comedy focus, although I think Nisekoi dives a bit deeper into the romantic aspect of rom-coms. 

Similarities: The same harem based anime..... Dissimilarities: In one anime the guy was just too pathetic, while in the other anime the guy seemly accpets his harem.
