I switched to iOS this past year after using Android since the G1, and working as an Android developer for the past 5 or so years. Pretty happy with the iPhone X, less happy with iOS 11, I think previous iterations were better.

Things I like:

* typing feels much nicer, no lag in character input

* phone runs much cooler, does not make hand sweaty to hold

* far fewer random freezes or lag

* password management much better by default, every app with important information has faceid which is quite nice

* I prefer the photos taken by the iPhone camera

* I find tethering on iPhone works more consistently

Things I don’t like:

* no back button

* some Google apps for iOS don’t seem as good as their android counterparts. YouTube app keeps getting buggy updates, Inbox still doesn’t support full iPhone X screen.

* Prefer Android’s notification system

* A bunch of apps have video playback issues, I suspect there’s an OS level bug
