One of the hidden benefits of the iPhone SE, is the ability to touch more of the screen with just one hand, or reach all the corners the phone with just one thumb, which makes the iPhone SE at least 1000 times better than even the iPhone pro.
The only competitor that iPhone SE has is the iPhone mini. However, the new benefit of the new iPhone SE is that it is actually newer than iPhone mini. Even newer than a iPhone pro. It seems on a superficial technological level, the best phone is the newest one. Or the best technology is the newest one which got released the most recently.
