I had the X for 10 months before it was stolen. And now I have the Xs Max. I think the X/Xs size is really good, I don’t see too much of a difference with the max. Yeah it barely fits in my holder in my car, and is large in some pockets, but none of those have been deal breakers. If I still had the X I would have been happy sticking with it for another couple of years. I always wanted a plus sized phone (regretted getting the 6, thought it was enough of a size upgrade from a 3.5 inch 4s!) so once the max came out I jumped on it. I love it but the X/Xs is great too.
