Is there an unequal contest where the much harder worm gear meshes with a much softer gear metal such as bronze or brass ? Or should this be on a mechanics forum ? A Ferrari gear box would not last five minutes with such a mismatch . That must disqualify some of the prettier designs . Are these "smoothies " with ball bearings best used with auto tuners ? How much extra would you pay if they sprayed some sparkle dust on them ?
Well, if I take your question serious: I don't think it's a problem of grinding material away, because actually there is not so much turning. Apart from winding up new strings and winding down old strings there is only very little actual rotation worth mentioning. In terms of friction, there is less friction between different metals than between same metals; Polished steel on brass in the better tuners is actually a very durable and smooth working combination. With the small amounts of material used they could CNC parts of any material that would suit an engineers fancy without too much changing the costs.
As to the ball bearings they don't make so much difference in smoothness. They mainly prevent squeaking of the tuners in the wood while tuning, especially after a longer standstill.
And with the decoration it's to your hearts' fancy: if you pay for it, you can get diamond dust coating or big rubys inlayed into the knobs
