Kakashi is considered one of the strongest shinobi in the entire Naruto series.
His notoriety as the copycat ninja and Chidori creator bulked up the legends of his strength.
The son of the White Wolf might've not exactly had the best childhood, but there's no denying the fact that these trials and tribulations helped him focus solely on his development as a ninja, which definitely paid dividends.
The fact that he became the Hokage is proof enough of the fact that Kakashi is one of the most powerful shinobi of all time.
