Wait u don't think Alchemist works dope with Nas?
I think Alc's work, with the exception of "One Never Knows", is sub par compared to Nas's works with Premo/Large Pro/Salaam Remi/LES. Even random nikkas like Hill Inc and Hillie Hill (same person?) who made "Level 7", which is a better beat than almost anything Alc ever made with Nas.
Consistency is key. If you're gonna go to the regulars, go to the dudes who've made career highlights. Y'all saying Nas should work with No ID, a weak ass producer who has made zero classic (or close) Nas tracks despite the number of times he's gotten Nas in the studio.
Otherwise, work with new randoms because they might have fire.
