I think the XR will ultimately go down like the 5C did.
If I wanted to save money I would buy last year's iPhone X rather than the XR.
That said, I think it's dumb that people claim the XR will be a "badge of shame". Once there's a case on it nobody but a few tech dorks will be able to tell what model you have.
The Xr has a different camera on the back vs the X/Xs. It'll be rather obvious to anyone who cares.
