After putting the polishes on my nail they really are just about identical and the most noticeable difference is that each polish has a different color ratio in its glitter. Surprisingly the easiest one to apply was Hard Candy's "Pop-arazzi" while Ciaté's "Comic Strip" and Sally Hansen's "Carnival" had watery formula's that made it difficult to get the glitter on to my nails.
Overall it's clearly visible that Ciaté's "Comic Strip," Hard Candy's "Pop-arazzi," and Sally Hansen Xtreme Wear's "Carnival" are nearly identical and unless you are a crazy nail polish collector (like me) then you don't need all three of these polishes. Out of the three I think the best one is Hard Candy's "Pop-arazzi" because it was easy to apply and is relatively inexpensive. The worst one of the three is Sally Hansen Xtreme Wear's "Carnival" because the formula was so watery that it was impossible to get glitter on the nail but the clear base made a big goopy spot on the nail. (For comparisons sake I applied one coat of each polish to see how the glitter distributed.)
