So, should I buy an iPhone 15, iPhone 15 Plus, iPhone 15 Pro, or iPhone 15 Pro Max?

Compared simply to one another, and ignoring earlier and later models, it can be a difficult decision between the iPhone 15, iPhone 15 Plus, iPhone 15 Pro, and iPhone 15 Pro Max.

There are two "smaller" models with 6.1" displays -- the entry-level iPhone 15 and higher-end iPhone 15 Pro -- and two "larger" models with 6.7" displays -- the entry-level iPhone 15 Plus and higher-end iPhone 15 Pro Max. The "Pro" models in each size originally were at least US$200 more than the equivalent non-Pro option.

Of course, now that the "Pro" models are available used, the price has dropped, but at least comparing used models from both lines, the "Pro" options should remain a bit more expensive.

The extra money for the upgrade to the "Pro" model of either size gets you (1) a substantially higher quality display, (2) 15%-17% more performance, (3) more RAM, (4) a bit better battery life, (5) a much more advanced rear camera with support for a more professional file format and video codec, (6) the potentially useful "Action" button, (7) faster USB 3 charging over USB-C, and (8) and LiDAR support. At additional cost, you also have (9) the option of more storage. Starting with iOS 18, (10) the "Pro" models additionally support Apple Intelligence (AI) features, whereas the entry-level models do not.

Although the iPhone 15 and iPhone 15 Plus are well worth considering for someone on a budget, the iPhone 15 Pro and iPhone 15 Pro Max provide a lot of extra value for the extra money. For many users, the (1) better display and/or (2) better camera already may be worth it, but the (3) faster performance provided by a newer processor architecture and (4) more RAM likely means a longer usable lifespan and an overall lower cost of ownership on an annual basis for someone who takes good care of their hardware, as well. Running iOS 18, the addition of (5) Apple Intelligence (AI) features may prove to be valuable to you, too.

Of course, for those on a tight budget, any number of other used iPhone models are certainly worth considering, also.
