The clearest difference is update cadence: X at every 3 weeks against Class With Catherine's every 12 months. X also leads on ratings volume (440 vs 16). Class With Catherine's advantage is review sentiment (100% vs 75%) and monetization model (free vs ad-supported). On price, rating, ads and in-app purchases there is nothing between them.
