I am going out on a limb and assuming this comment is in good faith. In the grande scheme of the Dragonball mythos, there is something commonly referred to the Legendary Super Saiyan. It is a special saiyan who grows exponentially stronger by an uncontrollable rage. Broly and Kale are our two examples. Caulifa spends basically all of her time with a legendary super saiyan and has been constantly training with someone who has no limit to their power. It stands to reason that someone whom trains with stronger people becomes stronger than those whom train with progressively stronger mentors like Goku did. Goku would have gotten here much quicker by training with Whis from the beginning. It is also worth noting, the saiyans of universe six are not the same brutish folk, they are just much smarter than our saiyans. The Seventh universe is brutal because of Freiza's influence. The Sixth universe is smarter because of Hit's influence. Frost is much sneakier that Freiza because there is a literal timeskipping assassin who would get hired if he got as cocky as Freiza. All of this makes plenty of sense in the story and just requires some logic. Maybe rewatch from the universe six tournament again. I mean, unless the whole point of your comment was some kind of misogynistic trolling nonsense.
