I think ruwo's route in matsurika no kei is perfect there were a lot of unexpected twists and turns that you couldn't have predicted, it's very thrilling and fun
Ukyos route and good ending in Amnesia can do NO wrong. That route genuinely changed my brain chemistry im not even kidding, I cried so much and contemplated so much on how far people go to be with the people they love, ugh the tragicness and loneliness of his character actually keeps me up at night
Shiraishi, I didnt expect to like him but I really enjoyed his route. Probably the best route in the game imo, the ending is pretty ass though the parts before it are so good i still consider it as perfect lol
honestly, xyx;s and toasty's route from blooming panic!! it seemed like the devs took good notes into better developing the characters between the initial release and full version. xyx is just so charming to me and for a true route i think toasty easily clears (maybe in part due to how engaging the game lore is itself)
