Zoya/Sinful Colors Dupe?? hmmmm

While swatching some polishes onto color wheels I ran across two bottles of pink polish that I thought looked strikingly similar, so I decided a comparison was warranted!

Zoya's "Sweet"

Sinful Colors' "Cotton Candy"

As you can see in the photos they are not the dupes I thought they were. Both seem to be a creme polish, both opaque in 2 coats, but Zoya's "Sweet" on the right is a bit darker than Sinful Colors' "Cotton Candy" on the left. I think they are definitely similar though!
