Verdict
The clearest difference is ads: Casty at none against Read Boost's shown. Casty also leads on update cadence (every 2 days vs every 5 months) and monetization model (free vs ad-supported). Read Boost's advantage is ratings volume (3 vs 1). On price, rating, in-app purchases and device support there is nothing between them.
