You don’t need to be confrontational, especially since I wasn’t arguing. Yes, the screen is smaller but it is by no means significant. I’ve owned 2 pluses and now the x and I can say I love the X and in no way mind the slightly narrower width. Also, I was requesting the source from the person who wrote about 2.6%, which that poster promptly responded. If you felt the need to respond to me that is fine, but you come off as a bit patronizing.
I do want to address your claim of misleading marketing. Selling screens by the size of the diagonal has been in practice for years and used by every major manufacturer/reseller of nearly every type of display. Also, Apple never advertised the iPhone X as larger than the Plus. This claim by you is in fact misleading and a misrepresentation of Apple.
Moving on, I don’t think there is anything more to add to this thread. The X is smaller, but in my OPINION the better phone. It all comes down to personal preference.
