If you have Adobe Acrobat Pro why not use its builtin OCR capability? Certainly you paid enough for it. Quite honestly since I got Evernote most of my work goes through it and I have found its OCR to be very reliable and accurate. The software that came with my Fujitso Scansnap scanner also has a very satisfactory OCR capability. Although I do not use it often, it is simply easier and more direct to use other tools, PDF Pen has good OCR capability.
There all sorts of applications with builtin OCR ability but often the trick is finding out where it is hidden the menus.
