I've been watching a whole lot of shounen anime over the last few years, and I have to say, the way they portray a dramatic fight between two rivals after a long buildup is so damned gratifying.

Off the top of my head, Hunter x Hunter's (Spoiler:) Gon vs Hisoka at Heavens Arena, (Spoiler:) Tanjiro vs Rui near the end of the first season of Demon Slayer, and pretty much any time (Spoiler:) Deku and Kacchan fight in My Hero Academia.
