Today I have a comparison with Illamasqua's Baptiste to W7's Purple Paradise as requested. I thought when trying Baptiste it had similar properties to Purple Paradise. So on to the comparison.
As you can see, similar but not total dupes. Both Baptiste and Purple Paradise contain that gorgeous pink iridescent shimmer, although Baptiste is darker and blue toned. W7's Purple Paradise is more of a red toned purple. This is two coats of both on the comparison shots (can't remember on the full swatches?). Purple Paradise was thicker but had more of that glow while Baptiste was for me the better formula as it was more opaque in 1 coat and applied evenly. Price wise, a big difference. Illasmasqua polishes retail for £13.50 each, while W7 retails at £1.99.
Do you need both? Erm... I'm going to say maybe as they are different toned purples on the same wave length. Depends on if you are a collector or a bargain hunter. Both polishes are stunning.
