Verdict
The clearest difference is update cadence: Antimicrobial Guide at every 3 weeks against Merck Manual Professional's every 4 months. Antimicrobial Guide also leads on rating (5.0 vs 4.8) and iOS requirement (7.0 vs 13.0). Merck Manual Professional's advantage is ratings volume (1.1K vs 2). On price, ads, in-app purchases and monetization model there is nothing between them.
