Ended up watching The Quintessential Quintuplets after that earlier ask, and I can definitely understand why people recommend the manga in that ones case. Vague spoilers:
the girl he ends up choosing is the least developed of the five and I feel like the decision came out of left field. Literally every other character has more development and hints as to why it might be her. I was pretty sure I had it narrowed down to two options, with one of them I was near certain would be the one and the one did choose came out of left field and felt so unexpected and unearned. Apparently shes built up more in the manga and I can see it being more enjoyable that way. Overall though, even if he had chose a character that got more development, not generally what I go for in my animes. Story kept me engaged enough, but I feel like it might have been portrayed better had it been written by a woman and not had all the unnecessary lewdness in it.
