when choosing a pcb vendor we can give some general info:
using pocket operators as a reference, the durability and quality mostly comes from the pcb being so thick. there is no real difference in material from any vendor, so choose a thickness that you are comfortable with.
the surface look and feel comes from using a matte black solder mask as the top surface. it's a simple way to get a nice design.
pro-tip: ask what kind of solder masks are available, and see if they can provide some nice colors.
