Originally I decided not to upgrade from my X but the more I started watching some of the early reviews the more I wanted the XS and particularly for the camera features. Stopped in to my local T-Mobile store this morning at 8am and grabbed a gold 64GB XS (not Max)...taking some sample shots around the house this morning I can tell you that the improvements in highlights and shadows are tremendous! Apple really did a fantastic job with their dynamic HDR, wow. I also really love the new aperture slider. The speed improvements are slight but noticeable as well.
