I am going to be getting an iPhone X and I don't know which color to get. I want the space grey but I know that it might flake down the road, and the silver will scratch easily. I am going to use a case but I really that that can scratch too. Has anyone with a space grey X had any flaking of the coating? Please let me know if you have and which color is better, and maybe what case would be best to protect. Thanks!!!
