Pros:

* works out of the box

* text to speech available in many languages!!

* Audio output in .wav -> easily convertible into something else

* automatically creates chapters based on the book

The limitations are: * the voices are very "AI"-style, so they sound emotionless, we're far from anything resembling any kind of acting;

* the conversion of a book into an audiobook might just crash if the script encounters a character that it doesn't know how to convert.
