Teachers - can you easily recognize which font a paper used? Does it impact how you view the paper?

Sure, it’s pretty easy to tell the difference between Times New Roman and Courier New – but what about the difference between Ariel, Helvetica, and Veranda and other san-serif fonts? Would you rather a student turn in a paper that’s the minimum page number in Ariel or a smaller font, or a few more than the minimum in a larger font like Veranda or Courier New (this is assuming you give students a choice)?
