Stickers are for tool boxes. Gaudy, tacky, childish. I'd rather see a really nice headbadge showing off the maker's marque and an understated paint job.
The components and the choices of tones and colors of different parts as they work together are the details I want to see on a well-made bike -not a bunch of tasteless stickers slapped all over the side or a gauche paint job that makes the bike look like an ice cream truck designed to draw in 11-year olds addicted to sugar confections...
But that's just my opinion -the tweenie-boppers might have another one.
