Verdict
The clearest difference is in-app purchases: Ad Testing at none against HTML Viewer Pro's 2. Ad Testing also leads on update cadence (every 4 months vs every 15 months). HTML Viewer Pro's advantage is review sentiment (49% vs 33%) and ratings volume (45 vs 6). On price, rating, ads and monetization model there is nothing between them.
