Onyx Vs. M.O.P.?

Now we know that these were some of the Grimiest groups back in the day but who do yall prefer? I remember singing "Slam" back in the day to "How Bout Some " and just to let some of yall know 50 Cents first appearance on wax was on "React" with Onxy so all yall 50 lovers should check that out, because he killed it. Anyway back to the question Onyx or M.O.P. ??
