40 and Legit are both sick as fuck and they compliment each other very well. I would have picked Legit a couple years back since I had all his albums, but started getting into 40's older shit and the more I listen to 40, I realized how dope 40 was. So many bay rappers use 40's lines in their intro or hook, that tells you a lot.
Both have different styles, both are sick as fuck, I can't choose either if I had to pick between the two. Damn, now I got to go get federal, mailman, tryna get a buck, down n dirty and game related and put it in the ride for rotation.
