Kai.
You'll notice a difference in Goku's tone of dialogue in Kai which is actually representative of what the manga represents of him. Unlike the OG DBZ, the Kai version of Goku sounds more harsh and cares more for fighting rather than being a true hero.
Goku not being a role model hero aint some good thing. There's a reason we capped for him hard and it's more than he was just super strong. We already got Vegeta for those betas out there that just want some moron super obsessed with fighting
