The article notes:
My recommendation: if you are only going to use non-rotated rectangular maps, consider the doubled or offset system that matches your map orientation. For maps with Rotation, or non-rectangularly shaped maps, use axial/cube. Either choose to store the s coordinate (cube), or calculate it when needed as -q-r (axial).
