They both suck since neither can do everything

Silver is still a finish. Every colour is anodized onto the aluminium; I’ve sanded enough of them to find out. I have only seen the problem on space Grey, which just happens to be the most popular. Rose gold is unaffected, like the silver. I don’t know about the midnight colour, but I don’t THINK it had the problem

You can get the residue off, but Apple Space Grey is notorious for sticker burn. The discolouration does not come off; the coating is that colour permanently.
