Tell us who you'd prefer draw Mob Psycho 100 or tell us if you like ONE's art.
I like ONE's style because it's really interesting how he can make good manga without relying on pretty art. Because of ONE's art limitation, he can't rely on fanservice or nice art and actually has to make interesting characters.
His main characters look like a child's doodles, but they have WAY more depth than the most well-drawn characters in the most popular shounen manga.
He pretty much single-handedly breaks all the assumptions that Bakuman makes (you need fanservice and bad artists can only make gag manga).
