I just don't see how Zion from Zion I is considered a great lyricist....that foo is a coo rapper and has nice concepts, but the dood is not all that dope....
Saying mac dre isn't a lyricist is just as ignorant as saying jay-z isn't original and is a biter....Mac Dre dumbed down his lyrics, but still had tight wordplay and coo punchlines...he also had style that gelled his lyrics alltogether
saying all of hiero is corny, cuz tajai and phesto aren't that tight...
from the bay, I'd have to go with:
Yukmouth
Casual
Ya Boy
Del
Bailey
Locksmith
Clyde Carson
Murs (even tho he stays in LA now, he started rappin up here)
Pep Love
Gift of Gab from blackalicious (well he's from davis, but close enough)
there's plenty more...but those are either on top of their game or are dope now and only getting better
