What make up is better MAC studio fix powder or Clinique superpower double face make up?

I want good coverage that will cover my scars i have a couple of pimples but not that bad its just scars mostly that i want good coverage on. My face gets oily if i'm to much in the sun. PLEASE HELP! I'm going to purchase one of these this weekend but i want to hear some reviews on which product you think is better.
