I'm not saying it's physical power. But I often see people mentioning Superboy Prime altering reality as if he just randomly punched into the air and his pure strength caused reality to warp.
And it's rather difficult to vote in this challenge. Superboy Prime might have Pre-Crisis like Power levels, but then again he got pummeled several times by a weak slowpoke like Conner.
Gohan has had combat training since he was a child, landscaped shake when he fights and what he lacks in physical strength, he no doubt makes up for it with Chi.
