I only get a single scene hmm. I’m way too indecisive for this so don’t pay much attention to order.
Little Busters!: Kanata’s Route Wedding Busters Yes it’s actually not that scene. The scene from Kanata’s route just perfectly encapsulates the essence of LB! for me.
Clannad: The flower-field and the first scene. Flower-field shouldn’t need an explanation and the prologue is just establishes the mood perfectly. I guess it becomes intriguing because it’s extremely dull.
Air: Misuzu’s death, this is the climax of the whole story so it’s the cookie-cutter choice. What’s good about this scene? Well what’s not amazing about it, is more accurate. The music is used so perfectly with Aozora playing, first it’s just the instrumental then the lyrics come in when the tension is at max. I think Misuzu is one of the strongest characters ever and this scene is just one of many that show that. How she strives to reach her goal is just so good, I can’t throw enough adjective at it. Now that I think about it, this may be my #1 of all time but I’m not sure.
I can’t pick out a single one for Kanon or Rewrite. They both have many things of equal value so I can’t choose.
