You can make things look real in corona as well just know how.
Modeling, Texturing, Shading, Lighting, Composition, Color Grading.
I think Fstorm has a different tone maping method simillar to coronas but different. For example I could never get same effect comparing Vray with corona. Corona raw render always looks better. ALWAYS. I am not going to go into details.
BUT at the end of the day its not a render engine its the artist. But this saying is to DIEing slowly...
