Periwinkle Shimmer Comparison

Okay, so I caved and got Nicole by OPI Back to Reality TV, one of the CVS exclusives (at least for the moment it's an exclusive—seems these things have a way of popping up other places eventually). I am not mentioning the K-word associated with this, as those females get way more attention than they merit. This particular polish is a periwinkle with pink shimmer, pretty enough to get me to overlook the bottle and branding.



On the nail, the shimmer is fairly subtle, though in brighter lighting the pink does pop. These swatches are two coats, no top coat.





I noticed that this Nicole looked similar to one of the new Sinful Colors, Zeus.





On the nail, there is a slight difference; the shimmer particles in the Sinful look smaller to me and perhaps a touch less pink, and the base color appears a hair lighter in most conditions, though in others it seems darker, so I'm declaring Zeus a perfectly fine alternative to Back to Reality TV, especially since it's about six dollars cheaper. (Zeus also has the advantage of having no punctuation in its name; I've been leaving out the ellipsis between Reality and TV for the NOPI).


Top to bottom: NOPI, Sinful, NOPI, Sinful.


Sinful (top), NOPI (bottom).

What do you think? Close enough that one person doesn't need both? If so, which would you choose? Would you take the NOPI if it were free?
