Verdict
The clearest difference is review sentiment: FM Essential at 40% against M's 0%. FM Essential also leads on rating (3.0 vs 2.5) and ratings volume (70 vs 4). M's advantage is update cadence (every 3 weeks vs every 15 months) and iOS requirement (8.0 vs 16.0). On price, ads, in-app purchases and monetization model there is nothing between them.
