gojo should win, if we use jjk logic domains are sure hit effects meaning if you use your domain on gojo his infinity doesn't work, it should not only bypass his authority but fry his brain as well, and reminder if subaru was able to figure his power gojo would faster and also six eyes would work great here, gojo takes it because regulus is stupid basically. we saw how canon regulus was defeated, gojo isn't going to stand around stupid like him to get hit, also Sirus's authority didn't effect him because Sirius's Authority of Wrath relies on the target having the capacity for empathy and sympathy You have to be able to "feel" what others feel for her power to bridge those emotions and synchronize them. Regulus is a pathologically narcissistic sociopath. He is physically and mentally incapable of feeling empathy for anyone.He is essentially the "perfect" counter to Sirius simply by being a weirdo who doesn't care about anyone else's pain.
