A lot depends on the intended applications, some tiles are better for wet areas, while others are more recommended for backsplashes or dry areas of your home. In general, mand-made porcelain and ceramics are better for bathrooms, while natural stones such as marble, quartz, or granite while still often used in a bathroom setting require a lot more attention and maintenance.  Also, the place where the tile is made makes the difference, European tiles are usually of better quality than their American or Chinese counterparts
