Thing is Havoc sounded like your typical dope rapper over boom bap beats. He doesn't get his dues for his lyrical prowess, but ultimately he's like a Prince Po to Prodigy's Pharoahe Monch.
Prodigy is not only lyrically and technically superior, but he sounds like a grimy, no money having motherfukker that will just slit your throat after convincing you to give him a minute of your time.
It's really indescribable how dope he was in the 90's Mobb Deep run starting from The Infamous. Havoc was an excellent complementary piece, and of course produced some of the greatest music ever. To this day, I maintain that Havoc has the dopest drums in hip-hop. Some of the shyt on Hell on Earth was mind-blowing.
So I actually think they deserve equal credit all things considered, coz they mix like vodka and milk
BUT, rapping-wise, Prodigy is just way better in all facets.
