I love using matte top coat over glitter and shimmer polishes, but while I like the look of matte cremes, I usually think they make my hands look oily or greasy. However, the satin finish of the Orly Plastix collection gives a semi-matte finish that does not look my hands look oily at all. I really like the satin finish, and I wish there were some kind of satin top coat.
Aside from the finish, I quite like Retro Red. It covers very well and I like the color, though I wish it was actually red. If you don't like the satin finish, a similar color is Sephora by OPI Cover Me in Petals. Here are the two bottles side by side, and then my nails in Retro Red next to the $OPI bottle.
While I haven't swatched these side-by-side, I think they are quite similar, though they look quite a bit different in the bottle (probably due to the frosted glass of the Retro Red bottle). If you have Cover Me in Petals and you're not particularly fond of the satin finish, you probably don't need both. However, I'm glad I have both.
