What font have you found to work the best with OneNote's OCR feature?

I've been trying to do some OCR with Microsoft OneNote and am experimenting with what font seems to work the best. While some seem to be relatively good, I'm curious if anyone has any experience with OCR and has found a font to be nearly error proof? I found that Fixedsys causes errors at times, but not sure if something traditional like Courier or Helvetica would do better?
