Verdict
The clearest difference is update cadence: GTViewer at fortnightly against ArcGIS Earth's every 3 months. GTViewer also leads on rating (3.8 vs 3.5) and review sentiment (50% vs 35%). ArcGIS Earth's advantage is ratings volume (45 vs 4). On price, ads, in-app purchases and monetization model there is nothing between them.
