I do miss the one-handed size of the SE, besides that I love my new phone.

Here is what I wrote on why the switch;
 
The SE phone itself may be irrelevant, but the idea certainly is not. Many people like a smaller phone, and they’re generally cheaper. As Apple services become more important, so does a cheaper, smaller phone. If the high end market is slowing, then one way to get new users into the ecosystem is with a really nice cheaper/smaller phone. The Xr/11 bears that out I believe.
