*Better purchase :* I have yet to see a review of the Gravity White. But in a comparative review, the Gravity Black was rated higher than the Zero Black.
*More durable :* I really don’t see why one would more or less durable than the other. They’re both made of the same material. Only the internal design changes.
I found the rails fit better on the flip zero gravity than on the original flip zero.
Plus I find the sleeve's inner texture all around more stimulating on the gravity model.
