Both have had showings that would beat the other.
My initial thoughts are that guys at this level (Superman, Goku, Thor, Shazam etc) are all so physically extreme that strength and speed become irrelevant. When you can push planets, a 200lb body means nothing. Moving at near light speed invokes time dilation.
What becomes more relevant are their other powers and skills. Thor and Goku are highly trained and experienced fighters and they can also teleport. All of them have insane energy projection. Heat vision is more instant and precise but kamekameha can be controlled to follow an opponent.
The video about Superman having no limits is kinda true though. "I...have.....to....lift...this....huge.....weight....." And we know he will.
