I break out from MAC products, but honestly, they have better primer.
The foundation just adhere to the skin better with the MAC prep and prime whereas with MUFE's primer, I find that it sometimes works against it.. on my "not so good skin days," the mufe primer makes things worse.. it makes it look very obvious that I have makeup up in an ugly way.. even if I wear the thinnest layer of foundation..
Bobbi Brown also has something called the protective face base.. is pretty nice. it doesn't break me out, and is a bit more moisturizing than the MAC prep and prime
and just a note, you shouldn't rely on a primer or foundation to protect you from the sun.. usually they are less concentrated, and don't offer UVA protection which is what you really want to be getting..
