To me it's Powerblocks. The black graphics, hubs, etc, all work out for a modern, aggressive look. In my mind, skinwalls give a more retro vibe. They still look good, but not my style.
*I haven't run skinwalls in about twenty years, I kinda remember sidewall fragility issues, is that a thing still? I had a pair of Specialized Umma Gumma grey skinwalls that I rode until the sides were shredded and tattered
