I used eSim for a while when I first got a phone that supported eSim, because I wanted to make it harder for a thief to disable the phone tracking, but now my main phone is broken and I'm a bit annoyed at having to chat with customer support for half and hour to activate eSim on another device.
Using both. Just emigrated from the US but keeping my Fi number as I've still got roots there, meanwhile I can swap physical SIMs as I jockey services here.
