i prefer T Nutty to Quinn
The C.O.S album is hard to sit though, he does get boring after a while, his voice and steady paced flows are his strength but his lyrics repeat.
Irocc always jumps on tracks with a shit load of energy, you can hear his hungar, lyrics are always hard, but until Irocc do a full length solo, i can't compare
As for subject matter, its all pretty much the same kinda shit, neither one of em breakin new ground lyrically.
I think thats the true test of an artist, to make a full length solo and keep it interesting.
