My Choice: iPhone 16 Pro Max

While the iPhone 15 Plus offers excellent value, I would choose the iPhone 16 Pro Max. The performance difference between the A16 and A18 Pro, coupled with the 120Hz ProMotion display, would result in a significantly better user experience for my usage. I prioritize a fluid and responsive device, and I value the longer software support that comes with the newer model. The faster USB standard is also a benefit for my workflow. While the price premium is significant, the substantial upgrades justify the cost for me, as a user who values a top tier experience that will last for several years without feeling dated. The extra weight is a minor concern I can adjust to.
