For me its purely looks, has an upscale look to it. You arent gaining any efficiency due to using the resistor, though even without it the power savings arent going to help anything. They do offer longer life though.
Wont melt the wires, but without knowing the specific thermal resistance characteristics of the resistor chosen...I wont make a claim on melting the tape. With these higher wattage power resistors i would think it should a low value of C/W and the tape should be fine. You dont need to tape the resistor either, I was just lazy. You can also buy high temp tape if you want.
