Unpopular opinion but, if you use your phone intensively, and will profit from the improvements in CPU, GPU and Neural Engines that are coming with the A17, then I would wait.
This year’s Pro lineup will debut the A17 and that SoC is expected to be a big jump in performance and efficiency, like it was the A14, the A11 and the A9 back in the day.
However, if your use isn’t going to be intensive in that regard, or just use the camera occasionally, then I would go for the discounted 14 Pro Max.
The USB-C connector change is not important for me, to be honest, and I’m happy with the reliable lighting port. However, the big increase in CPU/GPU power, the better efficiency and the bigger RAM from the A17 (it’s rumored to increase from 6GB to 8GB), may be of use to some people, and will undoubtedly grant a longer lifespan with such increase in specs. It’s the expected jump to the 3nm process, after all.
Mind you, it will probably come with a price increase as well, so it’s up to you if it’s worth the extra money.
