The gloss and matt versions create quite different relationships with light. Gloss reflects more of what is happening around it, so the irregular surface becomes more noticeable as highlights move across the wall. This can bring a white tiled wall to life, particularly where it receives natural or directional light.
The matt finish is quieter. Without the same level of reflection, more attention falls on the shape and subtle texture of the individual tiles rather than the way they catch the light.
Neither is necessarily more "handmade" than the other — they simply emphasise different characteristics. If you want the wall to feel brighter and more luminous, gloss has an advantage. If you're drawn to a softer, more natural appearance, matt can be the better fit.
