Verdict
The clearest difference is review sentiment: TCam Viewer at 100% against USB's 18%. TCam Viewer also leads on rating (4.0 vs 2.0) and update cadence (fortnightly vs every 5 weeks). USB's advantage is in-app purchases (none vs 3) and ratings volume (29 vs 1). On price and ads there is nothing between them.
