Verdict

The call

The clearest difference is ads: MotionBook at none against CircleMaster's shown. MotionBook also leads on update cadence (every 6 weeks vs every 10 months) and ratings volume (3.5K vs 30). CircleMaster's advantage is review sentiment (100% vs 68%). On price, rating, in-app purchases and monetization model there is nothing between them.
