Around Christmas I bought a refurb iPhone XR. Was pretty much opposed because I wanted to stick with a smaller phone like my now replaced iPhone 6. However I have not found that the slightly larger XR creates any problem. It fits in my shirt pocket OK and the swipe up instead of a button is fine.

The iPhone X was the cat's meow back when it came out and I do not think much has changed even though the 11 and 12 and soon 13 are available. Do not plan on changing anytime soon. Paid $330 for it from Supplytronics.com and bought the refurb iPhone6 from BackMarket.com. Both worked out fine.
