The Mac faithful willmost likely have picked an xs variant.
Guilty!

But I was moving up from a 6s. That was one of the reasons I went for the Xs rather than Xr. I’ve small hands and the Xs is pretty much the same size of the 6s but with way more screen. The Xr is actually a tad bigger. It mattered enough to me to pay the extra $$ for the “s.”
I have to say, I’m LOVING the Xs. It’s not a “Wow” phone, like the first iPhone, but it is an Apple phone in that it “just works.” Fast and smooth in operation, the most beautiful photos I’ve ever taken, and Face ID.
I love, love, LOVE Face ID! For whatever reason, fingerprint never worked for me without issues. It’d be fine for a while, then completely stop working. I’d have to re-enter fingerprints, which would work for a while, then completely stop working. Rinse and repeat. Most times I was entering the password. No more! As Apple might hyperbole, Face ID is like “magic.” I lift the phone, and it unlocks, ready to go. I use apps and websites with no fingerprint or password required, just a glance at the phone. And I love that my reminders don’t appear on the lock screen till I look at it. For Face ID alone, I’m glad I got it.
When ever I show my phone to the curious, they’re impressed. Which makes me think the Xr will do well. For all intents and purposes it’s the Xs at a better price.
