Dude has point... I love SC as much as the next man but slander against that album (particularly in the booth) will get you negged into oblivion. OB4CL > SC
and Cube has a couples albums that are close too or near SC in terms of impact and influence.
As someone who has Ghost one notch above Cube (#3/4) I'll say Cube is unrivaled in Hip-hop with Death Certificate when it comes to solo albums and impact. Count in his legacy and as a solo artist he has more of a stamp on Hip-hop than Ghost, or almost any dude not named Pac.
However consistency matters, the more Cube blew the more his music suffered. I'm actually one of the dudes who believes he only really has two bad albums - the Peace disc and I Am The West.
It's not that he can't write, songs like Stand Tall, Laugh Now Cry Later and Gangsta Rap Made Me Do It are vintage Cube. But he'll fill up his albums with a lot of mediocre shyt that's obviously him on autopilot.
Ironically both Cube and Ghost are quite good using an old man flow, slowing it down without sounding flat out lazy (Gza). Ghost just always sounds creative too, Cube rarely does.
IMO you cantwlose either way but it's obvious to me which of the two cares more about the craft at this point (and it's obvious looking at their careers why that might be).
