Everything I quoted in my previous comments are on the combat prowess and knowledge for the skill here, and I did post proof and situations about it.
Here is Goku's skill:
"While he lacks knowledge when it comes to things that aren't related to fighting, Goku is a master of prodigal skill when it comes to martial arts, with years of experience fighting against powerful opponents with a plethora of abilities. His skill when it comes to combat and the usage of ki allows him to replicate other ki-based techniques after seeing them once. He is a genius in combat and is capable of devising new applications of his techniques on the fly, such as using Kamehameha with his feet"
"Before adapting to Hit's time stop, he was able to predict the movements he'd make in the 0.1 seconds of frozen time and react properly. "
Additionally he had his combat skills praised by a guy whose is this skilled:
" As the God of Destruction, Beerus possesses millions of years of fighting experience, casually defeating the entirety of the Z Fighters with nothing more than a bored expression on his face. Due to his tutelage under Whis, Beerus has mastered a wide variety of martial arts and has extensive knowledge of pressure points, allowing him to instantly incapacitate foes of Goku's caliber with a single attack. However, for all his power and experience, Beerus' inability to find a proper sparring partner (outside of Whis) in Universe 7 has left him in a constant state of boredom and moodiness. As a result, he will often drag out fights for their entertainment on the rare occasion that he does find someone who manages to catch his eye (as he did with Goku despite his ability to easily defeat him at any time). In addition, he is far more interested in trying Earth's cuisine than paying attention to important objectives or potentially cataclysmic events, such as ignoring Frieza's rampage while enjoying a sundae and watching from the sidelines (which, to be frank, was somewhat justified at the time by the fact that Beerus was still far above the conqueror in terms of power)"
He matches people whose skill says:
"he is incredibly skilled in combat and has a knack for mimicking ki techniques, even after only seeing them once. Kid Buu is monstrous and almost animalistic in intelligence but retains his skill in combat and in replicating other techniques."
"Despite his young age and technical lack of experience, Cell has inherited the knowledge and skill of those he was created from. His combat skill and knowledge of ki allows him to immediately and easily see through the weaknesses of Trunks' new transformation, and in combat, he easily matched Goku. He was able to outmaneuver and escape Piccolo"
"Vegeta is a cunning and skilled warrior whose refined technique shocked Goku during their first fight, leaving such a lasting impression that Goku wished for him to stay alive so that he could surpass him. "
"He is skilled at reading his opponent's movements and constantly thinks out his strategies and motions in combat, to the point that Whis says he overthinks things. "
"Hit lives up to his title of "Never-Miss Hit", having gone over a thousand years without failing in a single assassination and killing his targets with a single blow. Though his skills mostly lie in the realm of assassination, leaving him lacking when it comes to non-lethal combat, Hit is an extremely skilled martial artist all the same, relying on his precision and finesse. His casual stance in battle, with his hands tucked into his pockets, allows him to conceal the movements of his fists in conjunction with his Time-Skip, leaving opponents incapable of properly reacting to his attacks as he suddenly strikes their vital points before they realize he's throwing a punch. Hit's no-nonsense approach to combat is incredibly effective, as he quickly and efficiently dispatches any threat with brutal yet graceful ease"
And he can easily outskill people who are this skilled:
"Her remarkable intuitive combat nature makes her able to master styles and transformations mid battle"
This is just by going off the profiles intelligence section and not bringing up every individual feat from each and every character
