Is full armor better or half armor better?

1, full armor means that the surface of the structure is completely covered with protective layer. For example, the exterior walls of buildings can be painted with nails and tiled.

2. Semi-armor means covering only a part of the surface of the structure. For example, the exterior wall of a building can only be painted without tiles.

3. The full armor is more protective and can better prevent the erosion of the external environment, while the half armor is relatively lighter and cheaper, but for some harsh environments, the protective effect is not ideal.
