Fable is great for interacting with others and having conversations about books, book clubs, buddy read etc. Storygraph is fantastic if you are a mood reader and look for books that bring a specific mood or trope. I personally care more about the cataloguing/subject matter of the books I read, so I stuck with Goodreads.
@Amber @Katharine Thank you for the input ladies. Looks like I'm going to use both, despite my best efforts 🤣
If you just get one, get Fable! Its most like Goodreads in terms of the social aspect. But I have both and I love Storygraph bc I can track so many reading goals and I get a complex breakdown of all the books I read!
