Not in order. (Except its cut in half by top 1-5 and 6-10)
1-5:
Lupe Fiasco
Joe Budden
Big L
Crooked I
Papoose
6-10:
Mos Def (Or "Yasiin Bey" these days)
Canibus
Cassidy
MF Doom
Nas
Honorable Mentions:
Pharoahe Monch (Literally on the edge of being in my top 10 except he'd have to push one of the 6-10 guys out.)
Joell Ortiz (Crazy schemes alone put him up there, but of course that's not even close to all he has to offer.)
Royce da 5'9 (Nice ass wordplay and punchlines. Dude is nice on the entertainment half too.)
Isaiah Rashad (Great artist and you can just feel the emotions in his music. Cilvia Demo easily became one of my favorite mixtapes of all time.)
Kendrick Lamar (Great artist and a nice lyricist.)
Slick Rick (One of the GOAT storytellers. You hear a Slick Rick LP and go on an adventure.)
TI (Somewhat of a Southern GOAT overall and has some nice ass project, and can rip a mic apart when he feels like it. Dude has nice multisyllabic whymes too. Reps the A town properly, a real ass n*gga)
Los is working his way into honorable mentions.
