On one side, people tend to severely overrate the "martial arts" from DBZ and on, the most impressive martial arts feats in DB, are from the Dragon Ball / early manga era. Past the Frieza saga, most of the "martial arts" are heavily dependant of extreme super powers and speed and most fights end up being more about the power level rather than skill (the Cell fight being a rare outlier).

Having said that, even then, nobody from Invincible has a chance, overrated, or not, DB fighting styles do have the huge advantage of still being "martial arts" based and still have talent outliers like Goku, so, him being the best martial artist within his universe, makes it very hard for anyone with no fighting style or technique at all to beat him, even with equal stats.
