With Amazeballs, I feel like the glitter looks slightly larger than normal and because of the density of the glitter, a mani with Amazeballs: Original makes it look like you have a sheet of metal over your nails. I expected the same for Soulstice, just in blue. But it didn't live up to my expectations. I have Amazeballs: Original, and when I use a jelly colour over it, the mani looks shinier than Soulstice looks on the nails.
I did have a better experience with another one of Lacquistry's lovely shinies, and I'll swatch that one at some point. :)
