His enunciation is usually on point, aside from a few songs, or did you meant the way he writes songs?
That's still how most of ATL raps their music, 3K took 2 albums to "get smarter" Outkast has ignorant shyt even for a few tracks on all their later albums after Aquemini. Then you have that double-album Pop crossover "WTF-ness" 3K did for his solo album, while Big Boi half of ironically raps with the same level of lyricism Future has now. Not saying he's a top tier lyricist, but compared to DS2, he has improved and also had his own moments on Honest.
