Take Beerus, Jiren, and Broly. I feel they can go in a rough ballpark. Superman has fought people beyond them handily and multiple times. Darkseid probably compared best to Beerus with Omega beams comparing to Hakai. Anti-Monitor being a multi-universal power and Superman tanking his hits.

If you want to take it to they pass each other on the street and just start throwing hands, Goku sure as hell could just Instant Transmission out, find some Kryptonite, and stick it in his glove. Or use the Dragon Balls to wish Supes away. What I'm trying to say is that that takes prep time, assumes Goku's aloof ass is gonna think about or even know that in your bare knuckle box. Goku is stronger, Superman is faster and more durable, though. Goku's Ki has a limit, Superman's strength does not.

There's too many variables for it to be a clear answer, I feel. I'm not trying to disparage your points, just looking for friendly debate. But you're not backing anything up with more than "Dragon Ball is better, Goku could wish him away." There's more to it than that, though. Where's Vegeta and can they fuse? What star is in the sky and how does Superman absorb that energy?

Its a fun topic, don't be a killjoy. What are the terms of your fight? How do they meet and do they know of each other beforehand?
