Yoriichi Tsugikuni is the strongest demon slayer character to have ever existed in the series. He is also the only person that Muzan was ever afraid of.
1 Giyu Tomioka, the Water Hashira
His personality, while characteristically stoic, is also protective and surprisingly passionate. Despite Shinobu's claim that Giyu isn't well-liked by the other Hashira, he may well be the most popular Hashira with the fans.
The young Tanjiro is not only one of the greatest demon slayers, but thanks to his kind nature, he's also one of the most honorable characters of the series. Tanjiro not only showed selflessness and love towards his sister and the people he cared for but even showed kindness towards his demonic enemies.

The secret to Gyomei's powers is that they are governed, regulated and enhanced by his emotional capabilities. So in a sense, his crying is a sign of his strength rather than weakness. As a gentle giant, Gyomei's character can be seen as a deconstruction of what makes a person strong in Demon Slayer.
