I don't know how anyone could prefer s2 artstyle nor animation. It's just worse in every way, less shadows, inconsistent shapes, looks like it was just drawn relatively quickly on paper. Not even talking about the animation because we've seen how that went during the Sukuna/Mahoraga fight 💀💀💀💀
S2 has a simple style, just lines without shadows. And animation where Mahoraga fights w Sukuna it’s most incomprehensible fight scene in whole anime world
