Compare to J7, J7 pro was also same fecher like 5.5 screen, camera 13 MP, chip set like Exynos 7 octa 7870, digital zoom, auto flash, face detection, touch to focus.ex.
J7 pro was finger print senser
64 gb inbiled
7.0 nougat
Sim slot comes in Nano + Nano
Screen to body ratio 401 ppi
So less features and a great cost for it so unresonable price
