One of the LDs I once talked to about MagicQ just said that it "is a HogII on steroids/HogII copy" (he is a big Vector guy),
It definitely has some Hog II similarities, mostly because of the shared personel between the design teams of the two, but it is definitely not a Hog II copy. Hog II on steroids might be closer to accurate. I have heard people describe MagicQ as "what the Hog III software should have been" and I'm not sure that is an unreasonable opinion. Regardless, MagicQ is thousand times more powerful than Hog II.
