Which foundation is better for covering problem skin: clinique or mac?

I think the Clinique will be better since it is specifically made for people with more sensitive or problem skin. Also, MAC foundations are notorious for breaking people out (especially the new Studio Sculpt). However, MAC does give better coverage, but it's nothing that some nice concealer below the foundation can not tod. So, just get the clinique, and if you need more coverage than get a MAC concealer (preferably the Studio Sculpt concealer) to wear underneath the Clinique foundation.
