Well, later last night I pulled out my NARS eyeshadow duo in Wicked. Looking up, I saw the Covergirl trio... and it was magic. The swatches come out very close. I'm not a big fan of Covergirl shadows, because I feel like the quality could be better. However, the understated greens of these two were so similar!
Wicked has two greens. The one on the left is a soft shimmery mint, and the right is a glowy soft lime. These are not in-your-face crazy colors. Now the Covergirl trio features Green Velvet, Seafoam, and Sun Sparkle. I only used Seafoam and Sun Sparkle for this comparison.
Seafoam is very close to the right side of the NARS duo. It has the same general shimmer; the only difference is a slight mute of color. There isn't as much of a "glow". As for Sun Sparkle, as compared to the left side, It also is very similar. The Covergirl version has a tiny hint more yellow.

|In sunlight, the colors look basically the same, except for the lime Wicked shadow. It's more vivid.|
My verdict? Not exactly the same. The tones of the two sets are off. I call this kind of conparison a quasi-dupe, because they're not exactly a dupe, but they could easily be used in the place of the original. Since they are so very close, it would be worth it to have the dupe, as opposed to a $30+ eyeshadow.
