Yahari Ore no Seishun Love Comedy wa Machigatteiru. Kan

Both deals with love triangle. The main character sometimes becomes indecisive which often leads to more confusion. Both of the MCs are good in study. If you liked WA2's wintery atmosphere, then you will like the warmth of spring in Oregairu.  

Both have MCs who likes to make excuses in order to run away from reality Both have a love triangle Overall atmosphere is similar too  

Both have similar type of MC. Both are slice-of-life type  

Some similarities can be drawn between the two series: - Main female protagonist look very much alike (Horikita and Yukinoshita) - Plot revolves primarily around school in both - MC's are kind of similar in that they are socially inept If you enjoy Oregairu you will most probably enjoy Classroom of the Elite too! 

Both romantic comedies, though saekano focuses more on harem (more girls). Both get serious when it comes to the relationships, especially more so during the 2nd seasons where relationships conflict. 

Both are romance and have more than 1 girl characters like the main boy. (Harem) And great art style. 

They're both great! Both are slice of life animes and the main character is a harem boi. Very honest and alone but they can be likeable if you just think of it as anime logic. Both are almost literally the same thing but just with some problems here and there. Also the main "heroine" is a black haired blond girl so yea. Overall its very great so ye 

Both of these anime are funny and both relating to clubs. I can say Haganai is pretty under rated but it was really good. Each character has a different personality and just having them in one club is good. I recommend this if you want something quite similar to Oregairu. 

fell. could, or should I say, should have learned from CloverWorks how to creatively adapt the end right, even though CloverWorks wasn't bright with Hor(rible)imiya, the very similar to Oregairu. 

Both experience having the taste of youth and friendship  

Similar plot progression. At some point you as the viewer lose hope, but all of the sudden it all comes to fruition. And makes any strife you've endured watching it worth it. 

I see, you maybe are now crying because an anime you have jst watched. Well, so you just finished Koe No Katachi or Oregairu and want something else, something different but not a lot, so, these are your titles. It may sound strange and out of context, but these two animes have a lot of similarities with ther MC, both of them are in the search of something else with the people around them, they want something, but they always thinks of their past and knows who the life works and that it will be difficult. The cast in general is also great in both animes, and sometimes you will love a character and later on hate it. It´s normal, don´t worry. read more 

Both are romantic comedies, but saekano focuses more on the harem aspect. Both shows delve into the more serious aspects of romance as relationships conflict with one another 

The two anime have many similarities. Each story is about a club created by their teacher for a group of outcast students that don't fit in with the other cliques. Both stories feature conflicts where the characters want the club to stay together as friends. The main male protagonists both have a martyr complex where they feel like they must sacrifice themselves for the good of others. There is also a love triangle between the main protagonists where they fear that confessing their feelings will break apart their grorup.
