well, I think it would depend on the finish you're after. I love both, but for different reasons. I actually use both daily. But I only use the moisture cream at night, unless I am particularly feeling dry that day (like winter lately here in Michigan)... it is NOT at all greasy or heavy to me (I assume you are referring to the new moisture feed/skin formulation?)
Strobe cream gives you a nice glow due to the shimmer effect-- however, if you're oily you may not be happy with it. I usually opt for strobe cream and mix it with my regular day SPF cream (honestly, I love cheap Olay for combo skin w/SPF like $10 for 4 ounces)...that way, I get a glow from the strobe cream but the little tube lasts
forever!! Just my .02 cents--sorry long winded but I HTH!!
