I use StoryGraph for my personal library management, but Goodreads simply has better coverage of both total books and specific metadata. But Audible is the best source anyway, as it has data specific to the audiobook other sources rarely do. I’ve included Goodreads mostly as a fallback for books Audible doesn’t have listed. One of the roadmap items is to add other sources, like Google books. At that time I would consider a source separate from Amazon/Google if a quality one can be found and conveniently called/scraped.
I’ve never tried it, but my father tells me that if you use ABS and include the ASIN in the metadata there’s a tool (possibly built in?) that can fetch chapter timestamps
