Apple

Was talking with a friend of mine about the range of iPhone models, and kept wondering if it's a mistake in buying the regular iPhone. Don't get me wrong, maybe some people don't want to spend extra money for some features that they will most probably never use, but the regular ones just miss some things(like the 120 Hz display) that should not be called "features" anymore nowadays. Also the chip is another thing that is messing with me. Like between the regular 13 and 14 the difference is the number on the box. Am I wrong?
