I get what you're saying, but Royce wasn't just stacking multis, he was showing a full display of his skill as an MC from a pure rapping perspective. Technically when Rakim and G Rap dropped their super lyrical songs, they wasn't saying anything other than talking about how amazing their rapping skills are. To me, that is part of rap. Just a display of natural talent. Flows, cadence switching, in and out of pockets, effortlessness in how he did it was amazing. I'm not about to downplay Royce's talent.
Lupe was pretty much freestyling or jotting down shyt and then saying it, without much concern for how it sounded or how it flowed. It was just a far better diss record because he was attacking his opponent and had scathing things to say.
The difference tho, with Rakim and G, you could just drop a song where you consider them being "super lyrical" and I could give you at least 10 quotables from each. You have to lightweight struggle to find a fire quotable in that 7 minute Royce song, lol. Royce is my guy, always has been...but ehh. I listened to that joint like 10 times trying to appreciate anything other than the rhyming/flow changes...aint nothing there G'z.
