Question of the Week #2: Cream, Liquid, or Powder Foundation?

This week's Question of the Week is about Foundations. Are you a cream, liquid, or powder wearer (or maybe even other)? I'm in the market for a new foundation so I'd love to know your current foundation (and your skintype!). 

I've been trying MAC Prolongwear Foundation (which is a liquid foundation) but sadly the shade I have, NC30 is a tad too orange on my skin. Otherwise I have been wearing a lot of my sadly discontinued MAC Studio Sculpt Concealer (which is a cream) all over my face.

Which foundation type do you favor? Any foundation recommendations to try or stay away from for my normal to oily skin?
