Verdict

The call

The clearest difference is review sentiment: Sheriff at 94% against AdBlocker's 20%. Sheriff also leads on update cadence (every 10 days vs monthly) and rating (4.4 vs 4.2). AdBlocker's advantage is ratings volume (90 vs 14) and iOS requirement (13.0 vs 16.0). On price, ads, in-app purchases and monetization model there is nothing between them.
