"PDF to Word with OCR” is best at recognition that I have seen
This has the most accurate OCR that I have seen. For a test document I used a TIFF image made by scanning a Xerox copy of a typewritten page. Some parts of the image are quite legible and some parts are pretty bad. I compared it to Acrobat Pro 9.5.5 and Acrobat Pro CC. "PDF to Word with OCR" did much better at recognizing than either of the Acrobat Pros.
I look forward to improvements such as multiple file input. But from now on "PDF to Word with OCR” will be my first choice.
