Yes, I also like classic fantasy battle shonen or seinen genres because it is cool to see the moves, attacks, and powers of the characters. It is even better If they have different character transformations as well such as Bleach with bankais, vollstandig, etc., DBZ with Super Saiya, One Piece with Devil Fruits transformations, etc. It is because they are so different from what we see on our normal lives and they are also unique from authors to authors. I think the reason why shonen genres is the most popular is because kids really love putting themselves as the cool characters with cool transformations and unique special moves.
Also, the comedy, romance, and the struggle/philosophy of shonen genres are closer to my taste compared to let's say more gloomy genres or romance-oriented genres.
