For this comparison I used 2 coats of each polish over Finger Paints base coat and no top coat. The polishes are Zoya Blaze on my thumb, Orly Miss Conduct on my index finger, OPI DS Extravagance on my middle finger, Zoya Aurora on my ring finger, and Color Club Gift of Sparkle on my pinky. I noticed no significant difference in application or formula between the Zoyas, OPI, and Orly. The Color Club was a bit thicker because of the glitter particles.

As you can see, there are similarities in color, but no dupes. I'd say Aurora and Gift of Sparkle are the closest color wise. Do you need all 5 of these? Maybe not, but they are definitely different enough to justify buying all of them if you like all 5.
