I agree but, i can usually discount this by the fact that one of the first things i say to people interested in my cubing is that it can be a sport and is not just a toy, you can be sponsored and everything.The outline of a black face behind a sticker just looks so sharp and classy. Its like a picture in a high quality frame or a photo with a nice mat. Stickerless cubes look considerably more childish, almost like a toddlers plastic toy to be beat up and destroyed, not loved and cared for. Stickered cubes look regal; as the cube ages the stickers give it character. Peeling, chips, and fading colors all give the cube personality that sticker less cubes lack.
As the cubes get bigger and bigger the sharp 90° grid created by the black lines beneath stickers just gets more and more visually satisfying. I absolutely love the look of a big cubes with stickers and "sticker maintenance" on these puzzles has never been a problem for me despite it being a common complaint of the masses.
