None of these are dupes. GOSH Holographic (index finger) and ChG OMG (ring finger) are linear holos, while ChG Let's Do It in 3-D (thumb), Essence Metal Babe (middle finger), and ChG Tronica (pinky finger) are dispersed holos. Tronica is most similar to Essence Metal Babe.
Which is your favorite? Although its the darkest of the bunch, I love Let's Do It in 3-D the best!
