This is the only shounen anime I’ve watched so far (that I remember watching complete).So by definition being the only one he is my “favorite” fighter anime?.
I’ve watch a couple of war animes , meaning that the use of guns in the battles and mostly not fists. However for favorite fight scene i’ll have another anime (but I think is not consider shounen).
PLUS: I’m watching boruto but I don’t think i’ll consider it my favorite fighter anime, at least not as it is now.(Yes I’m watching boruto without having seen a single episode of Naruto because ….¯\_(ツ)_/¯).
