Verdict
The clearest difference is price: Konbatas App at Free against EML Viewer's $1.99. Konbatas App also leads on rating (5.0 vs 3.0) and iOS requirement (15.0 vs 17.0). EML Viewer's advantage is ratings volume (21 vs 1). On update cadence, ads, in-app purchases and monetization model there is nothing between them.
