Why Finereader over DT’s own OCR ? - DT’s own OCR uses the Finereader engine and does very well at text recognition but doesn’t have some of Abbyy’s more advanced features such as compression or conversion to pdfa.
Why Finereader over Acrobat DC Pro ? - Adobe seems to have forgotten with their latest release that a measure of stability is an essential feature. Also your users will just love it when replace your awful non standard UI with an even more incomprehensible UI.
