Rechroming will require a stripdown which is why it costs more than a new chromed wheel.
Painted or powder coated wires eventually lose the coating around the spoke ends and may corrode. Wheel balance weights may also chip the paint so need touching up locally when removed.
So stainless wires are the least effort to keep looking good, even though new painted wires look amazing.
Oh and the centrelock nut grabs the paint and can make it difficult to get off. All this from personal experience.
