Evidence from Dilated Peoples.
Most improved rapper of all-time brehs. I didn't really care much for his solo work but he really stepped up his pen game as of late.

Resurrection > One Day...
All three I think got way more charismatic as their careers continued. That to me is one of the greatest elements of any rapper.
It's backwards. Most "emcees" when dropping their first album have all the lyrics in the world, but not that great of/even weak deliveries/charisma/artistry.
Whereas popular rappers' first albums show them as the opposite, where their lyrics aren't that great, but have delivery/charisma in spades.

Based on the fact that Ghost is one of my favorites now I didn't really think about it like that, but it's true.Ghostface. The leap he took from the Wu debut to becoming an arguably top 5 to 10 rapper in a lot of people's minds is amazing.
