(I don’t have any financial ties to this company or benefits related whatsoever ! I don’t know the designer personally.)
As for the traditional standard fonts, there are also differences in general readability. Do a google search to learn more. I’m not a graphic designer and would also need to read into this 
. The books I have on the subject are on the other side of the world, sorry.
