Ohw you can PM me your thoughts Philosopher, would love to hear it.
If anyone is annoyed by the derailment just say so and we can cut it off, but imo the prboelm with an actual battle between the two is two-fold: one, they both kill only when there's not other option. And secondly, superman's powers are extremely inconsistently portrayed, whereas Goku's powers are simply depended on which point in his life you take.
Therefore to me I came to the conclusion both have incarnations stronger then the other one, but during most of Goku's life, he's I would say strong enough to beat most incarnations of Superman. If you take Superman's strongest incarnation ever written in some cb somewhere, he's flat-out invincible and he'd probably destroy even Beerus.
However, I think DBZ is underestimated in just how powerful everyone is because it's practically unfathomable. Raditz is already completely invulnerable to bullet fire and he's the weakest enemy in the entire series, his power level is what, 300? 300 = bullets are useless.
Goku reaches milions upon milions upon milions.... I would be content with saying DBZ's powerlevel is near ********, especially post-namek, but the fact remains, I'd say, that most casual incarnations of Superman aren't anywhere near where the dbz characters are half the time of the show.
I'd go so far as to say the fusion of piccolo and kami could defeat most incarnations of superman. Let's remember that saiyan saga vegeta already has the power to destroy a planet, even barely without charging. That power level is already pretty rare for Superman to display.
Because Superman's powers change mostly because of different writers and incarnations, whereas Goku's powers change completely within the sole arc of the show, I say it's fair to say Goku beats Superman in the general sense.
I hope my signature negates the idea of bias here.
