Verdict
The clearest difference is ads: Security Protex at none against Opinion Ninja's shown. Security Protex also leads on rating (5.0 vs 4.6) and monetization model (free vs ad-supported). Opinion Ninja's advantage is ratings volume (57 vs 1) and update cadence (every 5 weeks vs every 4 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.
