I think their both nice, but I'm going to have to with Curren$y. K.R.I.T does his own production, and he has a deeper subject matter in some songs. But Curren$y just makes cool music, great work ethic, his beat selection is great, his rhymes are packed with fly pop culture references, and that laidback southern drawl compliments his production.
I don't think Spitta's made a wack project, Covert Coup, Pilot Talk 1 and 2, This Ain't No Mixtape, Cigarette Boats, Weekend at Burnies, Muscle Car Chronicles, Stoned Immaculate are all piff. I mean KRIT hasn't made a better album that Pilot Talk II and Covert Coup and Spitta has dope mixtapes and EP's to his name too.
Ones things for certain these guys are both underrated in the mainstream.
I don't know how some of y'all nikkas is saying "easily", and how is Curren$y anything like Soulja Slim?

Curren$y isn't really a gutter rapper.
