I haven't tried much, but their mascaras are great! I love the false lash effect. It doesn't live up to is name (but hey! No mascaras can give a false lash-effect, that is bullshit,) but it is great.
Their eyeshadows SUCK. Bad pigmentation, breaks easily and is very powdery.
Here in norway, the so called drugstore brands cost about the same as MAC, so I hardly buy anything else than mac.
