The (deleted) arguments are identical to the ones that were used
in previous centuries against the (then new) roman types versus
the (then common) fraktur typefaces. 

AFAIK, the only proven fact is that familiarity with a typeface
aids reading speed at the cost of decreasing attentiveness (due to 
reduction of your brain's active involvement in the reading process).

Specifically, I do not know about any quantified letter form research 
that does not add a disclaimer along the following lines:
 
  "results may be skewed (by an unknown amount) due to different 
   amounts of previous exposure"

Which is identical to: 
  
  "after testing a lot of american people, we have concluded that 
   english is the most natural of all human languages"

Until proven otherwise, I do not believe that there are rational 
arguments, only empirical ones. That does not make the empirical
argument invalid, however.
