MYK, Robert K S,
The best OCR I've used (for speed, accuracy, and interface) is Foxit Phantom. (uses the ABBYY OCR engine). Others are not even close. I have not tried Acrobat's OCR, but have not seen any encouraging reports on it.
But as with others I have tried, ABBYY recognizes strike-through and underline characters as unformatted text, thus corrupting the entire converted document.
Licensing ABBYY and then hiring a contractor to modify it to preserve underline and strikethrough characters is an unappealing option.
