It all goes down to the preference of the user! The only difference being the application and shelf life.
Sprays may last you longer due to the way the packaging is sealed allowing for more durability. A splash, however, allows you to apply the product directly to the skin, in crevices, and in desired portions.
So more importantly ask yourself, which is a better fit for your lifestyle? A spray which distributes the product at a measure and covers a designated region with a simple spritz. Or a splash which you may apply directly at your control and measure allowing for optimal and intentional use.
