I had them both for a little while, but twos a little much and I naturally ended up only using fable. The colors and interface are better imo and the team behind it seems to care more, theyre always updating it and actually listening to complaints. It might be more even with story graph now but I think in the future with a couple more features itll be better by a mile
That was my main drawback with story graph as well. Fable does have a bunch of stats, some are new and locked behind a paywall (one of the new updates I didn’t necessarily agree with) but it still lets you make a reading goal, track genres, ratings, and authors for free, and personally that’s all I really need. it also looks better and you can customize the colors
