First of all: Both types are better on V-Cubes than ANY stickers I have tried. At least, my 3 sets of V-Cubes have not a smooth and clean surface. This has to do with the production process.
Tiles make the V-Cubes perfect!!!
I have tried both, smooth and textured. It is really a matter of personal taste. Some people are getting goose bumps, when they feel the textured surface.
Originally, I had prefered textured, now I'm all for smooth. With smooth you are on the safe side regarding getting goose pimples
