I liked the form-factor and haptics of the iPhone X, compared to any other iPhone.
I still have the 4S. Will look into the SE successor.
I tried all of non-SE, non-X iPhones in the store and they seemed too "light" and a bit flimsy.
The all-glass iPhone X - while easily shattering when it does fall down - had a certain weight that made it comfortable to hold and yet wasn't as huge as the 8+.
So, it's either last year's X or an updated SE.
Whatever you say about the price, the X is a remarkable piece of technology.
