Do I choose Ditra or cementboard?

1. Ditra can be waterproof while cementboard allows water to pass through, but it won't cause any damage. The cementboard tile is mortared on the cementboard while the cementboard is mortared on the substrate. This creates a chemical bond. Ditra enthusiasts argue that this makes the tile more stable against movement.
