I think Conway is their premier artist on paper. In terms of style and personality though, I honestly think WSG is still the biggest "star" of the crew, despite being the least technical rapper. And I think Benny has more promise than Conway in terms of versatility. Conway is missing that "it" factor to be a front man, and even though he's the better technical rhymer than WSG and WSG wants to be the businessman and play the background...he is the one guy in the crew with the sort of "it" factor IMO.
I was saying after GOAT that Conway and WSG both work much better with each other than they do without, and I also think Conway and Benny sound better on tracks together than they do on solo tracks.
