I am looking to get a Sony Z ultra but I am worried about the coating. I have seen reviews about the coating rubbing off in as little as the first month or two in places of consistent scrolling or rubbing. Is the outer plastic shatter proofing easily scratched?

I am about a week or 2 away from getting a new device and would really like some feed back about these concerns from an owner. I hate Samsung and Touchwiz or I would just get the Note 3.
