One is going to tell you a relatable story like story of a nervous teenager and the first time he had sex, loosing his virginity or about a man who lived a troubled street life, died young, and left a message for his daughter so she would understand who he was, the struggles he faced, and the better future he hoped for her.
While the other one will tell you a story of a wealthy man who refuses to give a dollar to a homeless stranger, only to later realize the man was God testing his humility and compassion. Or the story of how his father once served a robber who later became his label boss, showing how one small act of kindness prevented a robbery that could have erased his entire existence.
Boths are amazing story telling rappers. Cole just edges it for me because of his relatability and simplicity.
