Tl;dr. If you have a good computer and don't mind some extra processing time and storage, then FineReader produces a superior output. FineReader uses multiple cores if necessary, so as far as text recognition is concerned, FineReader is faster than Acrobat Pro DC. Note this with a caveat because when you first create an OCR project, it takes time to load ("add") pages, and exporting a recognized project takes longer. However, if adding pages is a means of preprocessing, I wouldn't mind this extra time because the resulting file has a superior quality to Acrobat's result. There are ways to customize the output in the Export dialogue, so play with it until the result is satisfying. Here is why I think the end quality is superior, assuming you are using the default settings and keeping the image (aka text under the image). The most noticeable difference is at the text edges — FineReader preserves the thickness of the characters, so the night/inverted mode works equally well as it is on the white paper. I played with the settings on Acrobat but with no luck — the output sort of eats away the edge, and as a result, the characters become thinner and edgier (doesn't mean any sharper). I haven't spent as much time comparing the picture quality. FineReader's output files are generally much larger than Acrobat's and have less pixelating (haloing) around the line edges.
