Actually, the linked comparison is actually unhelpful

if it is about portraits. The linked page is entirely about

blur in out of focus parts. And as such, it didnt,t even use

comparable lenses. A 50/1.8 against a 85/1.4.

 

With the same line of thought, one could have shown, that 

using comraable settings leads to absolutely comparable results,

and therefore Crop-1.6 is as good as FF if it comes

toportraits.

 

On top of that ... comparing a studio portrait, where oof-blur

is next to unimportant, would have shown that crop-1.6 can 

even be a slight advantage .... that is if you want the whole

face sharp.
