Talefish PRO:

-I like the Sailfish nativeness of the program.

-clean design and presentation, well worked out features

-directory based file management trigers you to keep track of where you keep the files - stress reduction because "in control".

Talefish CON is a whishlist:

-no chapters.. Look at Listenbook on iOS and Voice on Android.
-no bookmarks & notes
-no integrated (sleep) timer
