Verdict
The clearest difference is rating: Write a letter at 3.9 against AI+Pro's 3.3. Write a letter also leads on review sentiment (27% vs 0%) and ratings volume (28 vs 3). AI+Pro's advantage is update cadence (every 3 weeks vs every 3 months) and iOS requirement (15.1 vs 26.0). On price, ads, in-app purchases and monetization model there is nothing between them.
