Iphone 6 or nikon d5200?

Which should i buy?
Dslrs are obviously not handy as compared to an iphone, so if the image quality is moreover the same (i maybe wrong), so then should i consider the iphone?

Substitute D5300 or D5500 maybe, because shopping the too-long-discontinued is usually not a good deal.
Anyway, the DSLR is potentially able to deliver better image quality.
The iPhone can make phone calls.

There are some premium compacts that have very good image quality that can fit on a belt.
