royce da 5'9 - has gotten worse over the past few years. he has some killer rhymes, but his verses are mostly hit-or-miss. some are really amazing, and some are just meh. then again, you can say the same thing about tupac and biggie. though he has exchanged lyrical fast-paced intense complex bars for short simple ones.
Joe Budden - was a great rapper. is still a great rapper.
Joell Ortiz - has had the biggest improvement overall. my favorite of the group now. his lyrics have always been good, but he improved his delivery a lot.
Crooked I - easily the most lyrical of the group. he's gotten better. of all 4 members, the experience of working together pushed crooked i the hardest to perform well. he is the least known member, but one of the best, being able to shine in the group in a way he couldn't solo.
