Nope. I would rather get a last-gen option second hand because there is very little difference between the 15 and 16. Perhaps the dedicated camera button, but that's it. I thought Apple would differentiate by giving their Apple Intelligence only to these new phones or only the pro models, but that is not the case.
If all current apple phones have the same AI capabilities, similar features, and similar performance, why would anyone get the latest model?
Yes, I know there are slight battery, screen, and performance/silicon differences, but the differences are not big enough to justify getting the latest model when the 15 is more than enough for most people and what they use a phone for.
