Verdict
The clearest difference is review sentiment: Metl AI at 90% against 小牛加速器's 17%. Metl AI also leads on rating (4.6 vs 4.3) and update cadence (every 3 days vs weekly). 小牛加速器's advantage is ratings volume (147 vs 9) and iOS requirement (15.6 vs 18.0). On price, ads, in-app purchases and monetization model there is nothing between them.
