Before you get either, I'd make absolutely sure you want to make that jump in size. I know the 11 Pro is more expensive, but it wouldn't feel as large as compared to your SE.
I can't say which you should go with between the XR to the 11. It really depends how much $100 means to you personally.
All I can say is either phone you go for, the size jump will take a bit of getting used to from the SE. I am just a bit over a week in and I am still not comfortable with the size. Funny as the phone I had before the SE is the same size as the 11, yet day two with the 11 I almost returned it due to proportions.
An older friend in similar upgrade time situation, from a 6yr old 5s. But does not really like any of the current iphones. All too big. 11 Pro is closest, but says he’ll never spend $1k on a phone. Probably end up w/ Xr or 11, not sure which.
