Why is the iPhone 7 Plus light years ahead of the previous iPhone?

People are still buying the iPhone 6s and iPhone 6s Plus. The iPhone 7 Plus is at least 10 years ahead of the iPhone 6s and iPhone 6s Plus. I can do so much more on my iPhone 7 Plus then I could ever do on an iPhone 7 iPhone 6s or iPhone 6s Plus. For example: Dual cameras portrait mode better low light camera and the camera on the iPhone 7 Plus is a MILLION times better than the iPhone 6s and iPhone 6s Plus camera. I can take MUCH better video on my iPhone 7 Plus then I could ever take on an iPhone 6s or iPhone 6s Plus. I also have a better screen resolution too and oh did I also mention that I have a touch sensitive keyboard 3D Touch and Live Photos. People don't buy the iPhone 6s or iPhone 6s Plus anymore. Just tell me the cold hearted truth: Why is he iPhone 7 Plus light years ahead of the previous iPhones?

No

Because it has headphone jack

The iPhone 7Plus is just a phone. Sure it has a camera, but it can't take pictures worth a darn compared to any of my cameras, including those that are 30+ years old, especially when you want to enlarge those pictures to anything larger than you'd want to see on a smaller screen, once you get past poster size, that nice sharp iPhone photos in the hands of 99.99% of the people out there, are not a great as they looked on the phones or laptops.

I haven't been able to find a phone that is more advanced than the Galaxy S5, If the iPhone 8 has a removable battery and a usb-c port and insurance that covers lost and theft I might consider it or if it sells for under $300 full actual price like my current LG Nexus 5x. Also has to have standard earbud jack in case I want to use the earbud I use in my sansa player in it.
