This is a raw photo from a OnePlus 6 taken with the default camera:
Both picture were taken from the same spot within 30 seconds of each other. I held each phone at the similar angles and locations to best compare the cameras. The differences are in the minute details, but at first and second look, they are nearly identical.
iPhone XS retails for $999 or so. OnePlus 6 was $349 as a certified refurbished device.
