The call

The clearest difference is rating: Worm. at 5.0 against StoryGraph's 4.5. Worm. also leads on in-app purchases (none vs 2) and review sentiment (100% vs 70%). StoryGraph's advantage is ratings volume (3.5K vs 31) and chart position (#22 vs unranked). On price, ads, device support and iOS requirement there is nothing between them.
