I have both and like both
Strada used to be a regular blush till it was dced. It look kinda blah beige brown in the pan but applied, it applies more as a neutral pink rather than the beige brown it looks in the pan. Some people use it for contouring, but I find that it's a bit too pink on me to work as a contour powder though it could appear differently on others.
Stark Naked was a LE beauty powder blush from quite a no of yrs back.. 2 or 3yrs back? I can't remember it exactly... but I'm not too sure if CCOs carry products from collections that are 2 to 3yrs back...
