Piccolo Daimao likely has the power advantage, given how high a pedestal post-Choshinsui Goku is treat until the finals with Tenshithands being amazed Goku could increase his strength far more than what it was 3 years ago and him considering a speed not too far above that Goku's as slow making Kuririn say a similar line of them being too far above him as he did with Ten oneshotting Taopaipai. Yamcha will cause Daimao difficulties with the Sokidan, but it won't be a game changer, unlike Daimao's Bakurikimaha which can obliterate an equal opponent if it hits directly. Daimao wins with high-diff.
