Sand is better for growth, but sometimes it is harder to keep them planted until they root. If you use gravel a layer of flourite under the gravel really helps.

The biggest problem I find with using substrates in layers is that they always get mixed up, when you add new plants, when you remove plants, when you do water changes, when you wanna add a slope here or remove one there. Stick to one substrate with about 3~5 inches in depth, give your plants a place to grow.
While sand looks really nice in some tanks, I find that Straight Flourite by Seachem works great and looks natural too. (Note: Flourite comes in 2 natural colors) Remember White Sand in a Planted Aquarium isn't going to stay that way, especially since you won't be vacumming on any regular bases. Because if you do, you'll be finding yourself replanting plants on a regular bases too. Also you'll need to replace sand on a regular bases if you use a vacum.
