Verdict
The clearest difference is rating: scrolly at 5.0 against LibraryThing's 3.5. scrolly also leads on review sentiment (86% vs 48%) and update cadence (weekly vs every 4 weeks). LibraryThing's advantage is ratings volume (278 vs 9) and chart position (#210 vs unranked). On price, ads, in-app purchases and monetization model there is nothing between them.
