Who is better? Who do you prefer? (Those are completely different questions) Who is actually more popular not currently name wise and amount of hits wise? Who would win in a "verzuz"?
I'll say Hit-Boy, Mike Will has some amazing tracks but Hit-Boy has more classics under his belt + is more versatile, like the same guy produced Cold and the new Nas album
(I do think Hit-Boy relies on loops too much tho)
