-Kakashi has surpassed Minato in some fields like: Ninjutsu, Genjutsu and Battle Tactics. IMO Minato only beats Kakashi and other hight level ninjas b/c of FTG tech.
-I feel like Kakashi has shown more skill than Minato in other fields excluding speed and sealing jutsu.
Minato in my book is only barely holding on to being strong b/c of his S/T jutsu and how easy it is for him to spam it in a fight.
Kakashi comapred to Minato
-Both can use Rasengan (Minato's isn't special other than the fact he may use FTG with it)
-Kakashi>Minato in ninjutsu
-Kakashi>Minato in genjutsu
-Minato>/=Kakashi in taijustu (maybe b/c Minato is faster but Kakashi does now the gates)
-Minato>Kakashi in sealing techs
-Kakashi>/=Minato in intelligence (of course this can be argued)
IMO they are about the same level if not Kakashi is a little better.... But I am biased b/c of the fact that I am not a fan of Minato at all.
Minato is much smarter than kakashi. Minato discovered how Tobi's S/T jutsu works and how to counter it in like 5 minutes. It took
the current team a much longer time to figure out how to counter tobis jutsu, and they actually figured it out by accident
