Considering that Rocky put Ferg on and that whole ASAP Worldwide brand rests on Rocky's shoulders, you just can't say Rocky sucks while being a huge Ferg fan. Ferg couldn't put himself on.
Rocky came out with the Bone Thugs flow mixed with a whole bunch of shyt. Ferg came through with the Bone Thugs flow. Full stop.
They use some of the same producers: VeryRvre, P On the Boards and Clams Casino.
It's the same sorta sound. It's just that Ferg goes into a more "turn up" direction while Rocky is cooler and artistic (but can still turn up, and when Rocky turns up, it's that dark 3-6 vibe. Not the modern trap shyt).
Rocky's sound and aesthetic is more dimensional to me. He has the turn up joints like Pretty Flacko, the 'jiggy' dance tunes like Goldie and Trilla, while also rocking the super laidback dreamy shyt like Leaf or Demons.
Ferg can't do that. Ferg = Shabba, and "Work" depending on if you like that track. He's a one-note rapper.
