Verdict

The call

The clearest difference is rating: Defender Guard at 4.6 against Mysa's 3.8. Defender Guard also leads on review sentiment (43% vs 30%) and ratings volume (4.2K vs 574). Mysa's advantage is in-app purchases (none vs 22) and update cadence (every 4 weeks vs every 4 months). On price, ads, monetization model and device support there is nothing between them.
