MAC Skin Visage SPF 50 is a dream primer. It differ's to the other MAC Primer as its not a silicone base so it's really good for all skin types as well as not being as "fussy" when it comes to application. The SPF 50 primer is a thick cream and leaves the skin feeling wonderfully soft and as its a thick cream, it can be applied as such whereas the other primer (as its a silicone base to even out skin texture) needs to be smoothed on, in long strokes or else it forms a matrix on the skin and can leave a residue and thats not good for your foundation application that's to come.
