I bought this foundation at the same time I bought Nars sheer glow. Since using both, I prefer the sheer glow, but the MAC foundation is good too.
I think it was nice to try out, I don't regret buying it, but I wouldn't buy it again. I also only used it a few times, and I've already hit pan.
Anyway, it's a really nice foundation, it applies well and feels nice on the skin, I just don't like it as much as Nars Sheer Glow.
